Real Madrid striker Cristiano Ronaldo would reportedly be open to the idea of joining Premier League champions Chelsea at the end of the season.

Speculation over the 32-year-old's future has grown since last summer, with Ronaldo thought to be unhappy in the Spanish capital having seen Madrid fall 19 points behind Barcelona in La Liga.

The five-time Ballon d'Or winner also faced allegations of tax evasion last year which are understood to have increased his desire to leave Spain.

A return to former club Manchester United has been suggested for a number of years now, but Ronaldo has also been linked with Chelsea and would be willing to return to the Premier League even if it meant playing for a different club to United.

The Mirror reports that Madrid could use Ronaldo in a deal to bring Eden Hazard to the Bernabeu, although the Portugal international has also been touted as a makeweight in a swap deal for Manchester United's David de Gea.

Ronaldo has previously insisted that he wants to stay with Los Blancos, where he has scored 426 goals in just 420 games, while United manager Jose Mourinho recently suggested that the Red Devils would be unable to re-sign the forward.
