Real Madrid star Cristiano Ronaldo is set to be put up for sale this summer.

Record says Real president Florentino Pérez has given the go-ahead to agent Jorge Mendes to listen to offers for the forward.

Ronaldo is anxious to leave Real Madrid after feeling a sense of betrayal with Florentino failing to keep his word and offer him a contract that stretches beyond his current deal which expires in 2021.

Ronaldo's ideal destination would be a move back to Manchester United, where he played between 2003 and 2009 before his big money move to the Spanish capital although reports suggest that an Old Trafford transfer could be complicated due to the high wage demands the striker from Madeira would insist on.

Despite winning three of the past four available Ballon d'Or awards the Madeira born player is the fifth best paid in the world with his 21 million euro annual salary.
