Manchester United manager Jose Mourinho is unsure over Zlatan Ibrahimovic’s future at Old Trafford, insisting he ‘doesn’t know’ what comes next for the player who now faces the prospect of several months on the sideline after sustaining knee ligament damage.

The Swede's contract at United expires at the end of the season and, following this fresh setback, the 35-year-old's future has now been thrown into doubt.

However, Mourinho, who suffered another injury blow ahead of Thursday's Manchester derby with the news midfielder Paul Pogba is out with a muscle injury, refused to discuss what comes next for the striker and insisted Ibrahimovic’s future rests in his own hands.

"Now he has important surgery, so I think it is a waste of time to speak about what comes next," said the United manager.

"I don't know, I don't want to know, I'm not interested in it, I don't care about it. I just want the difficult surgery to go well.

"The future is a big surgery, long period of recovery.

"But the future is also in the hands of a very strong guy, mentally very strong who wrote immediately in his social media he will stop when he wants, not when people think, so it looks to me that he is not going to give up, he is going to fight and I am really pleased with that. That is the Zlatan I know.

"I told him, 'You've fought all your life', so I don't see a reason not to fight.

"We think he is in fabulous hands and he has to recover from the injury and prepare himself mentally for the next step.

"I think the next step will be something he really wants, which is what I said before the injury in the period of doubt about his future.

"I always thought he is much more important than myself or what I want, it is what he wants.

"I always want players to be happy to choose their future and I think this is what is to happen."

A win on Thursday would lift United above Manchester City and into the top four, but Mourinho said stealing a march on their neighbours would only be relevant if it meant they secured Champions League football - which they can still achieve by winning the Europa League.

"It means nothing. If we finish fifth and they finish sixth and we are above them it means nothing," he added.

"If they finish third and we finish fourth they are above us, but it means a lot.

"This is not about Pep (Guardiola), this is not about City, it is about fighting for objectives.

"We want to play Champions League football and we still have two doors open."
