Central Midfielders: Ander Herrera, Nemanja Matic and Paul Pogba
Since Mourinho has always played his best teams with a midfield three, the best choice he currently has is Ander Herrera, Nemanja Matic and Paul Pogba. Herrera is an out and out fighter who's passion alone has endeared him to the United faithful. He has the engine to run back and forth, to hunt down the ball wherever it is. Also, the Spaniard, hailing from the Basque region, has a very sophisticated technique on the ball. He can pick a pass and come up with a goal here and there.
Matic is the most experienced holding midfielder at United at the moment and the Serbian is one of the first names on the team sheet. Mourinho's experiment on Andreas Pereira didn't last long,and Mourinho can consider himself lucky as he has a midfield general in Matic at his disposal.
It hasn't gone as well as expected for Paul Pogba since his return to Manchester United. But, there is huge potential in him and the French midfielder needs to concentrate on his football and not let off the field drama affect him. He has all it takes to be one of the best midfielders in the world. His Physique, Stamina and technical ability plus his ability to beat opposition players is seamless when he in his groove. He has all that is needed to be a complete midfielder. All he needs to do now is show it consistently and he can be the driving force behind a great United team.
