#4 Ronaldinho

The Brazilian legend is widely considered as one of the greatest footballers to have played the game. He has scored 94 goals in 207 appearances for the Catalan giants and led them to two La Liga titles and one UEFA Champions League titles. However, Pep Guardiola sold Ronaldinho in 2008 when he took charge of the club.
Though Ronaldinho’s last season at the club was his worst in Barcelona colors, he was only 28 and at the peak of his career. Though it was said that Pep Guardiola did not like his off-field life and decided to ship him off elsewhere, Ronaldinho himself quashed the rumors and said, “I was the one who decided to leave Barcelona in 2008, not Pep Guardiola."
Ronaldinho had a couple of great season with Milan and also led them to a Serie A title.
