Mata was sold by Mourinho back in January 2014 whilst at Chelsea, and many have questioned whether Fellaini and Blind suit Mourinho’s style of play.
It was reported earlier this week that the 53-year-old was planning to offload Mata and Blind to other clubs, with Everton expressing interest in the former.
However, Keegan claims that Mourinho is willing to give the trio a chance to prove their worth in pre-season.
The most vulnerable culprit of the Portuguese’s ruthless trimming of the squad appears to be Juan Mata: a technically gifted player, but one who lacks the speed, aggression and power that usually emblematises a Mourinho side.
Fellaini, whilst not necessarily popular with some supporters, offers a different dynamic and possesses a level of aggression that is likely to impress the manager.
Uncertainty surrounding Blind’s position at Man United stems from the fact that Mourinho prefers a steelier type of centre back. The Dutchman’s versatility, however, could be what preserves his status as a United player, and he’ll need to prove his competence at both left back and as a central midfielder if he is to avoid the chop.
