Rojo joined the Red Devils during Louis Van Gaal‘s reign and has so far survived the Portuguese managers time, even excelling and impressing him.
Capable of playing at left-back and centre-back, his versatility actually didn’t help with Mourinho as the boss became frustrated with him in the full-back position.
He was soon shifted back into the centre of defence and played his best games in a United shirt last season in that position.
Unfortunately for Marcos, he survived a nasty injury during the club’s Europa League campaign and has only just recovered recently.
Since returning from his injury though, Rojo now finds himself further down the pecking order and will need to fight for his spot once more.
Jose even thrusted him right into first team action rather than slowly introducing him back into the starting XI.
Bailly and Lindelof are two players who the Portuguese has personally invested in and so perhaps the Argentinian should be a little worried.
Jones is also another centre-back who has been hailed by the manager previously, having impressed during the start of the season.
Smalling may be the only defender who is a little dispensable to Mourinho, given the past criticism and sour relationship between the pair.
