5 top footballers sold by Jose Mourinho

#4 Leonardo Bonucci

Bonucci is, without a doubt, one of Europe's finest central defenders

The sale of the Italian centre-back has been one of Mourinho's greatest regrets as a football manager. While the majority of the players sold either wanted out of his clubs or were not quite good enough to play for him, Leonardo Bonucci was a promising Italian defender on the rise.

While Mourinho has the penchant of preferring experienced specialists over youngsters, he usually ensures that there is a buy-back clause on players with potential that he decides to let go of.

However, Bonucci's sale to Genoa for a few million pounds without any clauses for Inter to re-sign the player seemed to make no sense and left the fans disappointed.

Inter did manage to get Diego Milito in return, who helped guide the team to a treble win in 2010, but they would've had an assured centre-back presence should they have held on to Bonucci.

After moving to Genoa, he was transferred to Bari on a co-ownership deal before taking a massive step up when Juventus came calling in 2010.

Joining the Old Lady saw the Italian surge to great heights, becoming one of the world's best central defenders.

No longer at Juventus, Bonucci is plying his trade at Inter's local rivals AC Milan - who he joined for a reported £35 million.
