Everton boss David Moyes admits that he will not be able to stop Marouane Fellaini leaving if the club receives an offer that is 'right'.
Moyes has already confirmed that he handed the Belgian midfielder a dressing down after he commented whilst on international duty, that he could be in his last season at Goodison Park.
He only signed a new long-term contract last year, but he has been linked with a number of clubs this summer including Real Madrid and Manchester United.
Moyes was very unhappy with the midfielder for his comments, but he admits he would be powerless to stop him leaving if they got a big enough offer.
"I won't say there's no chance in the next window because everybody is available throughout the world if the offer is right," Moyes is quoted by the Mail on Sunday.
"But one thing I know is the transfer window is closed so he's not going anywhere right now."
Moyes also admits that he has no issues with any clubs 'circling' around his stars.
"I have got no problem if other clubs start circling for my players. None at all," he said in the Sunday Mirror.
"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.
"Whatever happens now, whatever Fellaini says, he is here for at least the next four months.
"He might be here even longer than that, I don't know.
"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."
