​As an Arsenal supporter who grew up during the Arsene Wegner era, I was always confused about the famous chant 1-nil-to-the-Arsenal. Wegner’s style of football was a very expansive and fluid way to play the game which resulted in great wins for the Gunners. In his later years, his approach remained somewhat the same in intention but became associated with physically weak players. This meant Arsenal were often bullied and fell short of victory. 

Accordingly, I wasn’t sure why Arsenal were ever associated with the famous chant that spoke of tight and unattractive victories because for as long as I could remember they either won beautifully or completely capitulated.

Of course, the famous chant harks back to a time of Arsenal’s history where they were led to success by George Graham who embraced a very defensive and pragmatic style of football. While I wasn’t around for this period, it’s safe to say I have become somewhat accustomed to this style of football throughout the last 9 months.

A frequent critique of Arsenal this season has been that they are an unattractive side to watch. I cannot dispute this. A lot of their games have been won by very tight margins, and this has led to more 1 nil victories than they have managed in previous seasons.

Arsenal have managed more victories this year which ended 1 nil (or nil 1) than they have in previous seasons where they finished second.

Furthermore, this year they managed as many 1 nil wins in the first half of the season as they did in the second half of the season (4) - with 3 of these coming in the final 4 games which led to the title. This is in stark contrast to the last two seasons where they managed just one 1 nil victory in their final 5 games and the 2023 season where they managed no 1 nil wins in their last five games.
​
As an Arsenal fan, I’m not quite sure how I feel about this. The presence of more 1 nil wins has certainly meant that I have had to endure a lot of matches that I didn’t enjoy watching. However, in previous seasons the absence of those 1 nil victories was associated with capitulation and key losses which ultimately resulted in no league title. Perhaps 1 nil wins late on in the season can be considered some kind of a proxy for grit or bottle. For my own sake I hope next year the Gunners can try to increase their number of 2 nil wins.

In eight days from now Arsenal will play in the UEFA Champions League final.  Twenty years ago Arsenal played their last final against Barcelona.  The final did not go to a penalty shootout.  If it had then one team would have an economist's analysis in their back pocket.  In 2006 Ignacio Palacios-Huerta was making a name for himself by examining data on penalty kicks.  As a scientist he was using data to test game theory.  As a potential advisor to a football team he was advocating a course of action for individual players.  Unfortunately for economists his ideas were not tested in the heat of the 2006 competition.

That changed two years later.  In 2008 he prepared a report for Chelsea.  That UEFA final between Chelsea and Manchester United did go to a penalty shootout.  As he explains in his TEDx talk, his advice nearly helped Chelsea win that title.

He later went on to write Beautiful Game Theory: How soccer can help economics.  Every sportsperson studying economics should read it.  Palacios-Huerta see economics as an approach rather than a subject matter.  Penalty kicks are the subject matter.  They provide the data for the questions this economist is seeking to answer, e.g. do humans behave as if they understand the complexity of strategy?  An understated feature of the book is the way it takes the reader through the 21st century economics approach to such matters.

The book starts with explaining the data collection and analysis process.  Palacios-Huerta explains how he uses data from the natural experiments that occurred in various soccer leagues.  He then explains how he replicated these natural experiments in a labratory setting with footballers.  Very few pieces of economic research are as robust.  The book format allows him to explain the difficulties of going from statistical averages to the analysis of the specific individual.  It is wonderfully illustrated by stories about Lionel Messi and Eric Cantona.

This thouroughness is continued in the book.  There is a chapter dedicated to the biological machinery and the neuroscience that is influencing economics.  A number of chapters dedicated to the psychological influences in behavioural economics.  Provided the student of economics likes soccer, and is prepared to work through some mathematics, it is one of the best introduction to economics they will find.

Last night’s Europa League final was not much of a contest. Aston Villa comfortably beat German side Freiburg 3-0 in Istanbul to become the sixth English side to win the competition. In the closing minutes, I remarked to friends that it is rare to win a major final so easily. As the clock ran into the 89th minute, I predicted two minutes of additional time. I was close – it was just one.

One minute of added time in a second half that had a goal, a caution, and ten substitutions. The substitutions alone stopped play for at least two minutes, and probably more. Why so little additional time? The scoreline, I suspect. 

​The same could be asked of the 2025 Champions League final. Zero minutes added at the end of the second half. The score: 5-0 to PSG.Referees are clearly influenced by the scoreline. Our recent paper in the Journal of Sports Economics validates this position. Had Aston Villa led 1-0 last night, my bet is that, under an identical second half (assuming no first-half goals), the fourth official would have added five or more minutes.

Why should a team winning 1-0 have to play more additional time than if they are winning 3-0? If referees are displaying compensation tendencies here, where else does this extend? Cautions, serious foul play, penalty decisions?
It is human nature to feel empathy towards losing teams. Adding just one minute when a team is losing by three goals in a major European final may feel like kindness or sympathy. It shouldn’t. It is not the job of the timekeeper to be empathetic towards the loser. Their job is to apply the rules and laws of the game.

Arsenal are on the verge of their first title since 2004.  The achievement is not exactly a Leicester City but it is surely a good news story for the game. However, there are some grumblings that they rely too much on set-pieces for their goals.  On Sunday, two hurling teams shared 53 scores totalling to 61 points.  At halftime the analysts waxed lyrical about the fact that so many of the scores came from play.  It speaks to a frequent complaint that hurling is turning into a free-taking competition.  Approximately 20% of the scores between Limerick and Waterford on Sunday came from free-shots.  Thirty percent (30%) is the current average for such games.

Last year, Tipperary won the All-Ireland title after playing seven games.  Over those seven games they averaged 30% from frees.  Thirty-five years earlier I was on a team that took five games to win the 1990 title.  We got 8% of our scores from frees.  While most would prefer a smaller proportion of scores to come from frees, most would also agree that the game in 2026 is in a better place.

In recent days, there has been speculation that Crystal Palace could financially benefit from a final day loss away to Arsenal. The source of this was based on the suggested nature of Eberechi Eze's contract, having joined the Gunners in August 2025 for an initial fee of £60 million. It is believed that £7.5 million in potential add-ons was included as part of a four-year deal with his new club.

Crucially, it is now believed that these add-ons do not include additional income for Crystal Palace if Eze's current club Arsenal win the league. Why? Because Arsenal's final league game of the season is away to Crystal Palace. Such a scenario, even if ignored and not acting as any perverse incentive to perform, would not be a good look for the game.

This begs the question of whether such add-ons should be permitted at all. One can reasonably assume that individual performance metrics, such as goals scored, number of assists, and so on, are reasonable to include. The chances of unintended consequences, while possible, remain limited, as these metrics are player-related only.

The introduction of team performance metrics into the contract of an individual player is a different matter. A player does not, in theory, have to play for team performance bonuses to be met. If a player signs for a new club and the buying club agrees to pay the selling club an additional sum should they win a trophy or qualify for European competition, these targets may be achieved entirely independent of the contribution of the player signed.

Such scenarios could give rise to a range of perverse incentives that alter the pay-offs from winning, or indeed losing, a game. It should never be the case that losing is more financially rewarding than winning.

A few weeks back Mikey Moore was named SPL young player of the year. His loan from Tottenham ought to be deemed successful. But is he an excpetion? In a new working paper with collegues in Ireland and the UK, we consider how the loan process affects later career pay of footballers. 

Loan moves are a staple of football for a long time now. Of course, the motivation for them and the loan/contract strcuture vary in type. For example, young players heading out to lower tiers to get first-team minutes or established players moving to new clubs on a trial basis. At times we see big-money flops being farmed out to revive their career. On the surface, it looks like a sensible arrangement for everyone involved, but our research suggests that for players, their may be an inter temprial cost of going on loan.

We use data for over 1,000 players in the English Premier League and Serie A between 2021 and 2025, and find that loan moves are consistently associated with lower wages. There is no evidence anywhere in the data that loans generate a later wage premium. Every type of loan, in both leagues, is either associated with a penalty or makes no difference at all.

We try to get at the idea of differnt loan motivations and find that not all loans are equal. The largest wage penalties attach to straight developmental loans, which see's young (u-21) players sent out with no purchase clause attached. Loans with a purchase clause attached to them, where the receiving club has an option to make the move permanent, carry smaller penalties. What about loans with an obligation to buy? Here we find no significant pay penalty at all.  This makes sense, as these arrangements are effectively staged transfers, and the wage already reflects where the player is going rather than where they came from.

Perhaps the most intersting finding in the research is the persistent effect of prior loan spells.  We find that for every additional loan a player has taken in their career, their wage is approximately 4% lower.  The labour market appears to be reading into a history of repeated loaning. When a player keeps getting moved on temporarily rather than integrated or sold permanently, its seems the market takes note.

The findings do differ across leagues. In the EPL, loans of any kind carry a significant wage penalty. Italy tells a different story entirely. In Serie A, only developmental straight loans attract a pay penalty. Every other loan type is statistically indistinguishable from non-loan wages. We think this is consistent with Italy's long-established 'loan culture'  where temporary moves of experienced players are routine.

As sports fans we often resemble the Jim Carrey character in Dumb and Dumber.  We can translate the smallest of probabilities into exaggerated hope.  Broadcasters play on it by producing some statistic that shows how the competitor that is ahead is prone to giving up a lead (or that the competitor that is behind is one of the better competitors at turning things around).  There's a chance.  An education in economics can innoculate a person but at a cost.  It can make hope seem dim and dimmer.

I was reminded of this at the weekend by two economists.  On Saturday, Ipswich were two goals up on QPR at halftime.  A victory would ensure automatic promotion to the Premier League.  At that point in time, I reminded an Ipswich fan, and economist, that Cork were 2 goals (or 6 points) ahead at halftime during the 2025 All-Ireland hurling final.  Cork would end up losing that game.  I suggested Ipswich might also lose.  His reply read, "No chance".  Ipswich won.

At halftime in the 2025 All-Ireland hurling final, one might have been inclined to think that Cork would win.  No team during the 2025 hurling championship had come from 6 points behind to win a game - until Tipperary did it to beat Cork in the final.  This is illustrated below where the thick red line is the All-Ireland final.  Tipperary had a chance (and a good chance given that they unlucky to be 2 goals behind).  The size of the turnaround was unusual.

Hurling-commentators frequently suggest that a large lead is easily overturned in hurling.  An economist I know can be "triggered" by such suggestions.  The data supports the economist.  But it can happen.  And, with better odds than made Jim Carrey happy.
