Juan Mata is set to stay at United following clear-the-air talks with Mourinho.
Mourinho sold Mata to United in 2013 while Chelsea boss but has no intention of ditching Mata again – even though he has warned the Spanish international he will not play every game.
He added: “I sold him because he asked for that. Nobody in my previous club wanted to sell or push him. It was his decision.
“He wanted to leave and my philosophy is I don’t want players who want to leave. I want players who want to stay.
“So we sold Juan, but I think since the first day here everything is clear between us. There is space for him. He’s a talented player.”
Juve, meanwhile, will target Newcastle ace Moussa Sissoko if Pogba leaves, but could face stiff competition from Everton, who are also interested in the £35m-rated midfielder.
