#3 Cesc Fabregas
Cesc Fabregas is the perfect example of how cruel and short-memoried the world of football can be. Upon his arrival from Barcelona in the summer of 2014, Fabregas immediately lit up the Premier League – even almost breaking the all-time Premier League assist record in his Chelsea debut season. His partnership with Diego Costa became a nightmare for Premier League defences, and aspersions were immediately cast on Wenger for missing out on signing him.
Fast forward three years, and Fabregas finds himself a part of yet another title favourite Chelsea squad – albeit at the periphery of it rather than pulling the strings. Chelsea's disastrous 2015-16 season exposed Fabregas' defensive flaws, and with the attacking positions occupied by Hazard, Pedro and Willian, there was no automatic starting spot for Fabregas anymore.
Even though Conte has repeatedly insisted Fabregas has a place in his squad, it is unlikely a player of his abilities will be satisfied by such limited playing time. A parting of the ways looks imminent in summer.
