Deportivo Saprissa (Costa Rica) and Al Sadd (Qatar) complete the podium with ten and nine players trained respectively, but none of whom have reached the knockout stage. The top three clubs for footballers whose teams have reached the knockout stage are AFC Ajax, Dinamo Zagreb and Sporting CP, with eight players trained in all three cases. Manchester City has trained footballers for the most national teams: six.

Six English clubs and a Welsh one are in the top 50 of the table: Manchester City (7 players trained), Liverpool (also 7), Chelsea (6), Swansea City (6), Arsenal (5), Manchester United (4) and Tottenham Hotspur (4).
