Supercomputer suggests Arsenal are on course for title

Arsenal have moved ahead in the title race as the Gunners took advantage of a consecutive Liverpool loss by beating West Ham 2-0 last weekend.

With Arsenal on top of the table heading into the international break, the football statisticians at 247Bet have run their predictive Supercomputer to reveal how the end-of-season table will look, and it’s good news for Gunners fans.

Supercomputer makes bold predictions on the 2025/26 title race after Gunners gain the advantage


The Science Behind the Supercomputer:

The supercomputer adopts the Monte Carlo method, at its heart is a Python-based match simulator that uses two Poisson distributions – one for the home team and one for the away team – to anticipate the number of goals each team could score in a match.

A Poisson distribution is a powerful mathematical concept that predicts the probability of a given number of events (in this case, goals) happening in a fixed interval of time. The key input to a Poisson distribution is the ‘lambda’ (λ) value, which represents the average rate of an event’s occurrence.

Let’s break this down using an example of Manchester City playing at home against Arsenal:

In our simulator, we first compute the λ for Man City, using both xG (Expected Goals) and actual goals scored per match based on their last 19 home games. This gives us an ‘attacking lambda’. For instance, with an xG of 2.24 and actual goals per match of 3.16 whilst playing at the Etihad Stadium, Man City’s attacking λ is: 2.7 – both xG and goals are used to measure both underlying and actual performance.

Next, we calculate Arsenal’s ‘defensive lambda’ based on their last 19 away games from their average goals conceded per game (0.95) and xGA (1.2) whilst on the road, giving a value of 1.08.

To tailor these λ values to the specific match-up, we adjust Man City’s attacking λ by factoring in the strength of Arsenal’s defence. We do this by calculating a multiplier, which is the ratio of Arsenal’s defensive λ to the league average defensive λ (1.54).

Multiplying Man City’s λ (2.7) by this factor adjusts it for Arsenal’s specific defensive strength. This adjusted λ better represents Man City’s goal-scoring likelihood against Arsenal. The same process is replicated for the away team.

In formulaic terms:

Home team λ = home team attacking λ * (away team defensive λ / league average away defensive λ)

Away team λ = away team attacking λ * (home team defensive λ / league average home defensive λ)
