The Swede is said to be in talks with LA Galaxy about an immediate move to the US.
"Zlatan is in his last year of his contract," Mourinho said. "If that is true and Zlatan wants a future in another country then we are here to help and create conditions for that to happen, not to make his life difficult."
The MLS transfer window opens next Wednesday, February 7, with suggestions in the US that Ibrahimovic would not take up a designated player slot.
Mourinho added: "He's told me nothing about it. The first time I read something or listen was from you. I read it on the web and on a television channel. He's never mentioned it to me so I don't know.
"The last thing Zlatan told me was that he wants to recover totally and help the team. He's working hard to be fit. I'm not saying he's injured, he's in a moment of trying to feel really ready."
