#4 Marouane Fellaini
The Belgian midfielder was one of David Moyes's favorite players. Fellaini has never been well received by the Old Trafford faithful and was seen as being responsible for costing the team points.
Fellaini is a short-tempered player and he easily gets into a feud with opponents. However, the player found the form of his life under the Portuguese boss, Jose Mourinho.
He was transformed from a "useless tree" to Paul Pogba's replacement ahead of Ander Herrera.
The Belgian came off the bench to net some crucial goals for Manchester United in 2017. With the World Cup upcoming, the midfielder wanted to move away from England in search of regular first-team action. Reports had linked him with a January move to Turkey.
However, Jose was reluctant to sell the player given the injury crisis in his squad. The player does not have any automatic extension left on his contract and is yet to sign a deal with United. His fate would be decided in the upcoming summer.
