Ibrahimovic has been linked with a move to LA Galaxy and reports circulated earlier this week saying he’d already signed the contract.
But Mourinho says Ibrahimovic hasn’t told him anything about a move.
“I don’t speak with players about media news,” Mourinho said.
“I see him every day, I am not working directly with him, for example today I was watching his work.
“He never mentioned absolutely anything to me, not an opinion, comment nothing at all, so I presume nothing is true in the news because I would probably be first to know from him, so I presume nothing.”
And the United boss is hoping he will be back for the Champions League clash at the end of the month.
