#2 Ander Herrera
Herrera has been one of the league's best midfielders this season. With more interceptions to his name (80) than PFA player of the year N'Golo Kante (79), the Spaniard is invaluable to a Manchester United midfield crying out for dynamism.
His marking out of Eden Hazard in the league clash against Chelsea caught the attention, but Herrera has been quietly brilliant all season. “He knows that he is having a phenomenal season for us,” Mourinho said back in December.

In Arsenal's new formation, he will be directly matching up against Sanchez and Ozil. Marking the duo will be a tricky task; but Herrera has proven his mettle in important clashes against Chelsea, Tottenham and Liverpool. His defensive nous and positioning could be key to keeping out Arsenal; but just as important, it could be key to the licence Pogba gets to run the game from midfield.
