#4 Papy Djilobodji
It would be harsh on the Senegalese defender to say he was a terrible player at his previous club. He had been a starter for over five seasons at FC Nantes in France, making over a hundred and fifty appearances for Nantes. The only problem though, was that Djilobodji had played three of the last five as of 2015 in the Ligue 2.
He was a decent player in a side that finished 13th and 14th in Ligue 1 in previous seasons. After a summer of going after John Stones, the only defender that Chelsea got was Djilobodji, who made just one League Cup appearance before a move to Sunderland that has oscillated between decent and terrible in 18 league appearances.
He would probably have been served better by a move to a mid-table Premier League side at most. That was not to be, however, and Djilobodji was not even given a proper chance at Chelsea. He complained that Chelsea manager Jose Mourinho had treated him unfairly by not even giving him a shot at the first team.
Djilobodji has now returned to France in a loan deal to Dijon, where he has made four appearances for the club.
