Real Madrid president Florentino Perez insists they will not sell Gareth Bale this summer.

Manchester United and Chelsea are chasing the Wales international for the end of the season.

"We would never listen to any offers for Bale no matter what the bid was," Perez said.

"He is a unique player who has already given so much to the team.

"He is the key to the club's future, just like I cannot imagine a future without Cristiano Ronaldo."
