UEFA Europa League 2022/23: Ranking clubs and groups with the Elo system – data analysis

The 2022/23 UEFA Europa League is set to be the 52nd edition of the second most important competition for European football clubs, known as the UEFA Cup until the 2008/09 season. The final will be played at the Puskás Aréna in Budapest, Hungary. Budapest was originally set to host the 2021/22 UEFA Europa League final.

The winner of the Europa League gets a place in the next UEFA Champions League and takes part in the UEFA Super Cup. Participants from Russia are excluded for the 2022/23 campaign. Spanish side Sevilla record winner of the competition. Last season, Eintracht Frankfurt won the cup.

In this data analysis, we will take a look at this UEFA Europa League campaign based on the Elo system. Additionally, in this analysis, we will discover data and statistics of all competitors.

How does it work?

Elo estimates the strength of a club based on the results against opponents and their strength. The Elo system works with only a single number, the Elo value. The difference in Elo points between two teams directly translates to a likelihood of winning against that team.

The expected number of Elo points gained from the next match is always zero. That means that over and underperforming over one or more games can be recognised by the number of Elo points won or lost in these games. That makes it very easy to actually judge how good a result or set of results has/have been.

Every game’s influence decreases when new games are played. In this way, a club’s Elo rating is a combination of all its previous results with games from the distant past having only a microscopic influence and the newest games influencing the rating the most.

To conclude, Elo ratings put a club’s results into perspective. Leagues vary greatly in quality and a metric that takes opposition strength into account is indispensable to compare clubs across leagues.

Overview

The Elo rating of all UEFA Champions League Competitors is within the range of 1,300 and 1,900. The average value of all attendees is 1,620. This is approximately the quality of clubs like Belgrad (1,636), Nantes (1,629) and Fenerbahce (1,597). The five weakest clubs are HJK Helsinki (1,318), Larnaca (1,459), Omonia Nikosia (1,471), Malmö (1,471) and Sheriff (1,479). The five best clubs are PSV Eindhoven (1,761), Union Berlin (1,761), Real Betis (1,793), Manchester United (1,822) and Arsenal (1,869).

Therefore, the likeliness to win the trophy for Arsenal is the highest, according to the Elo rating. However, the course of the knockout phase with possible opponents is not taken into account.
