#4 Marouane Fellaini
Marone Fellani was signed by the Red Devils in the summer of 2013 and many considered it a panic buy. But after 102 appearances for the club it is safe to say that he was a good buy. He has won 1 League Cup, 1 FA Cup and 1 Europa League with the club.
Jose Mourinho has often used him as an impact subsitute. Whenever United needs a goal he comes on and provides more aerial threat and this has worked for the Red Devils many times.
According to reports he could leave United as his contract expires at the end of the season. Though Jose wants the Belgian to stay at United but the club does not want to give him an extension.
But he need not worry as several clubs like Roma, Juventus and Inter Milan are said to be interested in the former Everton midfielder.
