While the Spanish global did see plenty of the ball, Rojo in particular stuck tightly to one of the Premier League's best strikers in an entertaining duel.
The Red Devils played in Russian Federation on Thursday night, so the game has been pushed back to Monday to give them more recovery time.
Nevertheless, it lies a distant sixth as Chelsea race clear at the top of the Premier League and Mourinho feels ready to settle in for the long haul, with plenty of work still to be done.
"It is not Chelsea's fault that we were given this Monday match, so we have to make changes for sure because we play Thursday against Rostov and they play Sunday against Terek Grozny".
According to Sun, the Chelsea manager is keen to sign the England worldwide to fit into the Italian's system as Conte looks to bolster his squad ahead of their return to the Champions League.
It will be interesting to see what kind of team Mourinho selects for the FA Cup match against Chelsea as Manchester United do not have any recognised striker available. "His history with Chelsea is great and I know very well he is in the hearts of the Chelsea fans and this is great because he deserves this". Am I happier to win against Chelsea than another team?
The United manager has been up to his usual tricks - moaning about fixture pile up; denigrating Chelsea's style of play and ultimately playing mind games, for which he has found an unworthy opponent in Chelsea's new adored manager, Antonio Conte. "Chelsea can only think about that because I think they are champions and have nothing else to play for".
"Also because they have had four days to recover [from their Europa League trip to Rostov]".
Speaking about Monday's FA Cup quarter-final, Mourinho claims he has the right players in place to break down their defensive approach.
"We have to keep getting points in the Premier League to let us go to the last months of the competition with that door open. So the Europa League is more important than the FA Cup for us". We can not go there with a [Reserve] team, we'll try to manage it within our squad and get a good team to compete with them. While he did look exhausted at the end of the match, the England global worked hard, looking to hold up the play on every occasion while chasing any loose balls that came his way.
