Real Madrid president Florentio Perez insists he has no intention of letting either Cristiano Ronaldo join Manchester United any time soon.
The superstar duo have been linked with a move to Old Trafford in recent months despite appearing settled at the Bernabeu.
Bale in particular has been the subject of much speculation. The former Tottenham ace has helped Los Blancos win the Champions League and the Copa del Rey in his short time in Spain, and has 11 goals in 22 games so far this term.
However it has been suggested that Bale is open to a switch to Manchester United and that Real Madrid could sell if the right bid came along. It is believed that the Red Devils were willing to pay £90 million for the Welshman.
Ronaldo meanwhile is perennially linked with a move back to Manchester United having left Old Trafford in 2009 for a then-record fee of £80 million. Now 29 and in the form of his life, Real Madrid were reportedly looking for £60 million for the Portuguese superstar.

However, despite all the speculation, Perez says there is no truth in the rumours that either Bale or Ronaldo could be sold any time soon, and insists the duo are key to Madrid's long-term plans.
"Bale is not for sale and we will never listen to any offers for him," he said. "I cannot imagine Real Madrid without Cristiano Ronaldo, nor Gareth Bale. This is a unique player who has already given us a lot and is crucial to the future of the club."
Last week Manchester United boss Louis van Gaal added fuel to the fire by seeming to hint that he'd been talking with executive vice-chairman Ed Woodward about a potential swoop for Bale.
The Red Devils spent in the region of £150 million last summer and are expected to do something similar at the end of the season - although their chances of spending that money on Bale or Ronaldo now look slim.
