#4 Luke Shaw
One player that has gotten his mojo back since Ole Gunnar Solskjaer's arrival has to be Luke Shaw. Under Jose Mourinho, Shaw was often a subject of criticism from the Portuguese manager and never looked like a settled member of the team. But that has changed since Ole took over.
Shaw currently looks like the fullback; United thought they were getting when they splashed out huge money to get from Southampton in 2014. He’s getting up and down the field comfortably, defending with great vigour and has even added a good number of assists to his arsenal.
When the United team sheet is read out before a game, you expect to see Shaw there unless he’s suspended or out with an injury.
Shaw has become quite dependable and assured for Manchester United, if he continues that way, United will not need to invest in the position for quite a long time.
