Issue number 268 of the CIES Football Observatory Weekly Post presents the percentage of league clubs.
Last Champions League finalists, Tottenham (5.0%) and Liverpool (8.3%), as well as domestic league minutes played by footballers signed at the start of the season for all of the big-5 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.
