Real Madrid president Florentino Perez feels ready to cash in on Cristiano Ronaldo this summer. Ronaldo has struggled for form since the New Year and Perez believes age is now catching up on the 30 year-old.

El Confidencial says the Real supremo is convinced the forward has entered the final stages of his career.

The news of Perez's willingness to sell Ronaldo will be a massive boost to Manchester United and Manchester City.

United are keen to re-sign the 30-year-old, who scored 118 goals in 292 appearances for the Red Devils.
