Real have seemingly been desperate to land De Gea for years. They nearly did in the summer of 2015, only to see the proposed £29m deal fall through because of a missed deadline, but the former Atletico Madrid youngster has remained loyal to United ever since.
He signed a new contract shortly after the 2015 debacle and another Mourinho has confirmed that another fresh deal is in the offing now that his current terms are beginning to near their expiration.
"I think he will stay," Mourinho is quoted as saying by the Daily Express. "I don't know what Real Madrid's intentions are, but if I were them, I would think of another player."
De Gea has further established himself as the bets goalkeeper in the world this season and would have been surprised not to be busier when United beat Liverpool at the weekend.
"A goalkeeper like he is and obviously a club that wants to be better and better and better, we are not going to let that year option go away. But obviously, we are going to try [for a new deal]," Mourinho continued, insisting that executive vice-chairman Ed Woodward is working hard.
"Mr Woodward is not on holiday. He barely has holidays. Of course he's going to try to give him a contract that keeps him here for much longer than that option that of course we are going to execute.
"I just trust the board and the work they do. I don't negotiate players, I don't discuss numbers and contracts."
