David De Gea has remained a target by Real Madrid after a supposed switch that did not happen a couple of years ago.
But Manchester United are keen on having De Gea stay with them as he is regarded as the best goalkeeper in Europe.
United have begun preliminary talks with the goalkeeper and are giving him a new long-term contract.
The Spain international will be out of contract by next season and has the option to extend the deal by another year.
Jose Mourinho admitted that the extension would be triggered if necessary but at this time, they want to secure a long-term future.
Talks are at a very early stage as De Gea’s representatives and United are still in negotiations.
Real tried and failed to sign the goal stopper in 2015 with De Gea signing a four-year deal with an extra year extension with United. But Real have maintained their interest on him ever since.
Mourinho was prepared to let go of De Gea last summer but the negotiations collapsed after Real focused their efforts on funding Kylian Mbappe who did not end with them but joined Paris St-Germain.
Now, Mourinho has changed his tune and is not interested in selling the goalkeeper.
“It’s obvious that we’re not going to let the option [in De Gea’s contract] disappear,” said Mourinho. “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 to give him a contract that keeps him here for much longer than that option that, of course, we are going to execute.
“I don’t discuss numbers and contracts. I just say what is obvious. Anyone of you would say the same – David is to keep.”
