Real Madrid star Cristiano Ronaldo acknowledged he could play in Major League Soccer before the end of his career.

The Portugal international has previously indicated he has no interest in playing in the United States, but appears to have had a change of heart.

Ronaldo told ITV back in November he wanted to retire "with dignity," adding: "That does not mean it's bad play in the leagues of the United States, Qatar or Dubai, but I do not see myself there."

A host of big names have chosen to finish their careers in MLS in recent seasons, including Didier Drogba, Steven Gerrard, Frank Lampard, Andrea Pirlo and David Villa.

Ronaldo acknowledges the standard of football has improved and claimed it could tempt him to make the move when he finally decides to leave the Bernabeu.

"Maybe in the future will be a good chance for me to play there [in America]," he told GQ. "You never know, but it's something interesting. I consider it, of course, because as I've said, soccer there has become better and better. ... I think that this is maybe going to be possible."

Ronaldo has been linked with an exit from the Bernabeu this summer, with interest from Paris Saint-Germain thought to be high.

But it remains to be seen whether the 30-year-old will be allowed to leave by Los Blancos, given their impending transfer ban.
