Manchester United and Real Madrid have been lined with the 24-year-old Belgian attacker Marouane Fellaini, who has made an impressive start to the English Premier League season.
Fellaini fuelled speculation of his possible departure from Everton when he recently said that the current campaign would be his last at Goodison Park.
"Whatever happens now, whatever Fellaini says, he is here for at least the next four months," Toffees manager, David Moyes told The Sunday Mirror. "He might be here even longer than that, I don't know.
"I have got no problem if other clubs start circling for my players. None at all.
"What I do know is that they can't come in and take any of my players until January and we are only in September.
"What I do know for certain, though, is that Fellaini has got a five-year contract here.
"So clubs can circle, but the window has just shut, and we're in a strong position as far as his contract is concerned."
