Roberto Mancini made a name for himself as a manager with Inter Milan in Serie A winning three consecutive titles (although one was stripped off Juve and awarded to Inter). His transfer to Manchester City signalled the coming of a new age at the club who were looking to find success with big money signings.
In came the likes of Sergio Aguero, Edin Dzeko and Yaya Toure and City eventually won the FA Cup in 2010/11 and the 2011/12 league title under Mancini in the final game of the season. However, a below-par season saw him move to Galatasaray where he did not see eye-to-eye with the board.
A move to Inter followed where he again spent big – especially on Geoffrey Kondogbia, Antonio Candreva and Ivan Perisic. But he would leave in the summer of 2016 and has been a free agent since.
