Top 5 players from the 21st century who became excellent managers 

#2 Diego Simeone

Simeone is a passionate coach

Diego Simone played as an all-action defensive midfielder for some notable clubs like Inter Milan, Sevilla, Lazio, and Atletico Madrid and won fans over due to his never-say-die attitude and passion with which he played the game.

His club career was littered with medals from multiple competitions including LaLiga, Serie A, and UEFA Super Cup.

It goes without saying that he was a bonafide Argentine regular and he won the Copa America on two occasions and retired as one of the greatest players in La Albiceleste history, having made a then-record 106 caps for Argentina.

Success has also come on the manager's bench and Simeone won led Argentine side Estudiantes to their first league title in 23 years in 2006, a feat he repeated with River Plate two years later.

His biggest exploits have, however, come at his former club Atletico Madrid who he has transformed from outsiders in Spain into one of the genuine heavyweights on the continent and his exploits in leading an unfancied side to the league title and Champions League final in 2014 ranks as one of the greatest in managerial history.
