#1 Juan Mata
Spanish and Manchester United attacking midfielder, Juan Mata is in his final year at the club as his contract comes to end in the summer of 2018. The 29-year-old might be allowed to leave the club for free at the end of the season, with Andreas Pereira possibly being the player who fits as a suitable option to replace Mata.
An important first-team player for United, Mata can help split open deep-lying defences with a single pass and is a very effective attacking option. Having scored a goal and recorded three assists so far this season, Mata has found regular time in the manager's rotation policy.
The Spaniard joined United from Chelsea in 2014 for a large fee in the region of £40m, and It will be interesting to see how Mourinho's deals with the next two transfer markets as United will be in for a complete overhaul this summer.
