Porto midfielder Joao Moutinho has put Chelsea on red alert after admitting he would consider a move to the Premier League.
The 25-year-old has been interesting the Blues for the last year and recent reports suggest they remain keen after the player helped Porto to another league title victory in Portugal.
He was heavily linked with a move to Stamford Bridge last summer when he was seen as a possible alternative to Luka Modric. And now the Portuguese international, who plays in central midfield, admits he cannot rule out a move to England.
He said: "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.
"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 is rated at £25m.
