Issue number 268 of the CIES Football Observatory Weekly Post presents the percentage of domestic league minutes played by footballers signed at the start of the season for all of the big-5 league clubs. Last Champions League finalists, Tottenham (5.0%) and Liverpool (8.3%), as well as Manchester City (7.7%), are among the 14 teams where new recruits played less than one tenth of minutes.
The figures for Manchester United and Chelsea are much higher: 25.8% and 33.6% respectively. Among Champions League participants, only LOSC Lille fielded new signings for a greater percentage of minutes than Chelsea: 42.5%. The highest proportion in the big-5 was measured for Fiorentina (69.5%), a club recently taken over by a new wealthy owner.
The most stable teams are to be found in the Premier League, where new recruits played so far only 15.7% of minutes (maximum 50.4% at Aston Villa). At the opposite end of the table is the Italian Serie A: 29.6% (minimum 5.5% for Atalanta). The averages measured in the other three leagues of the big-5 are 22.7% for Bundesliga, 24.0% for the Liga (maximum 54.3% for Sevilla) and 26.7% for Ligue 1.
