Manchester United goalkeeper David De Gea is set to sign a new £200,000-a-week deal at the Old Trafford.
Mourinho said: "He is a Manchester United player and will as soon as possible sign a new contract.
"Would I swap De Gea for any other keeper in the world? No.
"He likes it here, we love him.
"We want him to stay, so when a player is not on the market his value is zero."
The 27-year-old is widely considered to be the world’s top goalkeeper and kept 18 clean sheets in the Premier League before being named the Red Devil’s best player for the fourth time.
However, this season is not the best one for the goalie. Since the start of the world cup, he played 6 games, faced 14 shots on target and conceded 10 goals.
