Cristiano Ronaldo's potential return to Manchester United this summer could hinge on Tottenham star Gareth Bale, according to The Sun.
The report claims a successful Real Madrid bid for Gareth Bale will pave the way for a return to Old Trafford for Ronaldo.
Madrid have been strongly linked with a £85m bid for Bale - an offer that would break Ronaldo's £80m world transfer fee record set in 2009.
The Spurs winger could be the perfect replacement for Ronaldo, who's reportedly unhappy at the Bernabeu and has been mentioned as a possible target for big-spending French duo Monaco and Paris St Germain, as well as United.
But Madrid president Florentino Perez insists Ronaldo is going nowhere this summer, and plans to offer the 28-year-old forward a bumper pay rise to keep him in the Spanish capital.
"I would bet Cristiano will retire at Real Madrid," said Perez.
As for Bale, the Madrid chief remained coy on the possibility of a summer deal.
"For those players and investments that generate income, you can give everything in life," continued Perez.
"But we don't speak of Bale so much because he plays at a friendly club and they will be annoyed."
The report claims United believes Ronaldo would only leave the Bernabeu to return to Old Trafford, and have put together a £65m plus Nani or Javier Hernandez package just in case.
