Absolutely everyone loves percentages, so why not pick up the numbers from the 501st weekly report from the CIES Football Observatory. They compare 65 leagues around the world in terms of how long the coaches have managed the teams they now manage. On average, three out of four coaches have been in the job for less than a year (75.3%). This percentage rises to 100% in the top divisions of Costa Rica, Ecuador and Mexico.

With 19 out of 20 coaches who have been employed for less than a year, Italian Serie A has the lowest percentage among the European leagues analyzed. The only exception is Inter’s coach Simone Inzaghi. In comparison, 7 out of 18 coaches in the Dutch Eredivisie have managed their teams for a year or more – a record among Europe’s top divisions.

In the Eliteserien, the average length for head coaches is 306 days.

In terms of average seniority among the coaches in question, the figures range from 2 years and 67 days in the German Bundesliga to only 88 days in Costa Rica’s Primera División. The German record is partly due to the exceptional case of Frank Schmidt, who has led Heidenheim’s first team for almost 18 years. Diego Simeone (Atlético Madrid) and Brian Schmetzer (Seattle Sounders) complete the podium for coaches with the longest seniority.
