Olympique Marseille coach Igor Tudor is convinced by the potential of Arsenal loanee Nuno Tavares.
Tudor believes Tavares is good enough to play for any major club Europe - including Real Madrid, Barcelona and Manchester City.
Tudor said: "He's still a young player but he has fantastic physical capacities. He's got an outstanding ability to run.
He could play at Real, at Barcelona, at Manchester City.
"He still needs to grow and progress, we talk a lot to him."
