The two clubs have reportedly agreed upon a fee of £40m for the Serbian midfielder, according to Sky Sports.
Matic further fuelled the rumours when a photo surfaced on social media of him wearing a United jumper.
And now Mourinho has confirmed that the deal is close to being finalised.
“I’m waiting for news,” he said. “I know that he wants that very, very much and when a player wants very, very much the chance is bigger, so I think we have a chance, but in football until it’s official, I have seen so many things happen that I refuse to say more than I am telling you now.”
On the jumper photo, Mourinho added: “I don’t know because I was not there. Number 31 is a free number. It was [Bastian] Schweinsteiger. It’s a free jersey, we have a few free and 31 is one of them.”
