Major teams are built up over a period of years. The 63rd CIES Football Observatory Monthly Report presents an innovative approach to comparatively assess the sustainability of squads based on three elements: players’ age, the length of their stay in the employer club and the duration of their contracts.
According to these criteria, Manchester United currently has the most sustainable squad among the 98 big-5 league clubs.
Manchester United fans can thus be confident in the ability of their team to qualify without too much difficulty for the group stage of the Champions League over the next seasons, and eventually lift again the Premier League trophy.
Ranked just behind Manchester United despite having far fewer financial resources, the Basque clubs Real Sociedad and Athletic Club constitute perfect examples of sustainable squad management.
Conversely, Genoa is a perfect example of short-term planning.
While football is not an exact science, data analysis can be an important tool with which to optimise performance.
The sustainable squad management rating is not just a descriptive tool allowing the comparison of strategies pursued by teams in the past, which is interesting in itself, but also an instrument to steer future policies so as to increase the chances of success.
