FC Porto midfielder Joao Moutinho has refused to rule out the possibility of him one day joining a Premier League club.
The Portuguese international has long been linked with a switch to Chelsea.
Despite admitting that he is happy with his current employers, the 25-year-old has conceded that the English top flight is one of the "best leagues" in world football.
"Every player wants to experiment with different leagues. Right now I'm happy because I am playing in one of the biggest in Europe. But if a good opportunity arose we'd have to see," said Moutinho.
"The Premier League? I can only say it's one of the best leagues in the world - but I have not spoken with any club."
Moutinho joined Porto in 2010 from Sporting Lisbon.
