Former Real Madrid president Ramon Calderon believes Gareth Bale is disappointed with his Tottenham loan.

This week Bale said he was expecting to return to Madrid once his one-year loan spell came to an end, with another year left on his contract in the Spanish capital.

"He's not happy about his time at Tottenham and Mourinho doesn't seem to be very happy either," Calderon told talkSPORT.

"He's not counting on him in many matches and Bale is disappointed and maybe that's the reason he would like to return."

Calderon said he would need to work hard to win supporters back if he were to return to Zinedine Zidane's side.

"Fans are very volatile, it depends on his performances.

"If he's going to play well and score goals like he did when he came then fans will back him.

"But if he's not then problems will come again. This club is very demanding, I remember with Zidane they were booing him for the first five months because they thought we've paid a lot of money for a player that wasn't playing as they expected.

"I'm sure fans will be backing him if he does things well."
