The 545th CIES Football Observatory Weekly Post shows that 65.2% of teams across 55 leagues worldwide have changed their head coach at least once over the past year. This proportion is close to that recorded on the same date last year (see here). This finding reflects chronic instability in most clubs.
By league, the figures range from 100% of clubs having changed their manager over the past 365 days in the Cyprus top division (14 out of 14) to just 18.8% in Norway’s top tier (3 clubs out of 16). These disparities reflect the existence of considerable differences in the way clubs are managed, which are also visible at player level in terms of squad stability (see our Demographic Atlas).
The Post also presents data on the age of coaches (in this case, excluding those currently serving in an interim capacity). The overall average is 49.5 years, with the highest average age in Bulgaria (55.6 years; no coach under the age of 40) and the lowest in Sweden (43.5 years; 13 out of 16 under 40). With respect to age too, the geographical differences are striking.
