However, with the Red Devils scheduled to play their second game in the space of three days when they host the Russian giants on Tuesday, the former Real Madrid boss will make changes, though Mourinho stressed that Manchester United have not yet qualified for the next round and will have to get the job done.
"He's happy to play tomorrow", said Mourinho said.
"More importantly, the others deserve an opportunity to play". "Zlatan needs some time of very hard work on the muscular area that supports the knee that had the problem".
"When the period for that hard work comes, so does fatigue. His cycle of work will be over after CSKA". And he will be out again for tomorrow but I believe back to normal work after CSKA.
The boss later told reporters that Sergio Romero will start against CSKA Moscow with Joel Pereira on the bench as our back-up goalkeeper, providing David De Gea with a well-earned rest following his heroics against the Gunners at the Emirates Stadium on Saturday.
Manchester United have scored the opener in three of their last five meetings with CSKA and (1.28) is up for grabs with Bet365 for them to repeat the feat in this tie. My goalkeeper is always the best goalkeeper in the world.

"I am not going to make him play tomorrow so Matic is out". David is third best.
"I'd have to think", the manager said.
'Our young players will have something to learn from him playing in the game but at the same time we can not allow him to play at his best and show everything he is capable of'.
"We didn't qualify yet, we didn't finish first in the group yet, there are other clubs also involved in qualification and I need to keep a certain balance in the team".
But he will give Luke Shaw the chance to put himself in the shop window.
"Selected for Tuesday, yes for sure".More news: Arrest made in connection to NC Amber Alert case
