Major mistake: Mourinho should be forcing these 2 stars out of Man United to keep Martial

Juan Mata

Understandably, Juan Mata is a hugely popular figure at Old Trafford. Indeed, the Spaniard really is a wonderful player and one who constantly gives his all, though surely Martial is more important.

As good as Mata is, the 29-year-old has probably seen his best days now and, while he could do a job for a top team for a few years, should be sacrificed to allow Martial to flourish. The upsides Martial can offer sadly outweigh the ones Mata can, at this stage of his career.
