His fractured relationship with Mourinho was laid bare for all to see in a frosty exchange between the two on the training ground, which turned out to revolve around an Instagram video he posted during United's defeat to Derby County in the League Cup.
Mourinho is also at odds with Eric Bailly, the Ivory Coast global who is no longer first choice.

Mourinho is one such manager who does not care about how valuable a player could be for the club's fortunes, if his attitude is not where it is supposed to be, Jose will get him out of the club.
