The Tunisian Ligue 1 is the professional championship where we record the greatest number of coaches during the season with a percentage of 100%, the sixteen teams that are part of the elite.
According to a study by the CIES football observatory, which classifies 60 first division leagues worldwide, 487 teams out of the 850 analyzed, changed coach during the season, which corresponds to a percentage of 57.3%.
