Perez added: "We haven't spoken to De Gea".
However, the deal collapsed on the deadline day and De Gea continued at United.
Real Madrid have always been linked with a move to replace Zinedine Zidane's current No.1 Keylor Navas, despite his impressive performances.
De Gea, however, does appear set for a move to Madrid as a replacement for LaLiga and Champions League-winning keeper Keylor Navas. Why he wanted Gea before?
"Zidane saw him when he was 16 years old".
The emergence of 18-year-old Mbappe and Donnarumma's contract situation at AC Milan have caught the eyes of club chiefs in Madrid, though.
Perez has confirmed that Real are watching Donnarumma, but refused to reveal more details if his side would make an approach for the Serie A star goalkeeper.
"Everyone says he's a great player, he's going to be the substitute for Buffon", Perez said. And he seems to have very good manners.
But, according to Real Madrid president Florentino Perez, who this week won the election to continue in his position, rumours linking Real with De Gea are wide of the mark. "We're definitely following him, but I can't tell you everything we'll do". The Los Blancos have identified the Italian goalkeeper as a better alternative than the Red Devils stopper.
