Everton chairman Bill Kenwright admitted Marouane Fellaini could leave the club, with Manchester United, under former Toffees boss David Moyes, thought to be the leading candidates for the Belgian midfielder's signature.
With Moyes making a move to Old Trafford as Sir Alex Ferguson's replacement, it was inevitable that some of the better players at Everton would be linked with a move to United.
Fellaini reportedly tops that list, with Moyes keen to link up again with the 25-year-old at United, while also filling the void which has been felt so often in recent times in midfield.
Kenwright while speaking to Roberto Martinez, who was appointed new manager on Wednesday, insisted Everton will not sell their best players, but acknowledged the fact that Fellaini could indeed leave due to his buyout clause, believed to be around £24 million ($37.4 million).
"He (Martinez) talked about a couple of new signings and he talked about the squad and asked 'Do they need to go?,'" Kenwright said.
"I said 'No, they absolutely do not have to go' (although) there is one (Fellaini) that has a get-out which everyone knows."
Moyes will be keen to strengthen his side in the coming months, and working with a player familiar to him will also go a long way in helping the manager settle down quicker at the club.
Meanwhile, United right-back Rafael, who had an outstanding season for United, but yet could not find a place in the Brazil squad for the Confederations Cup, revealed his holiday plans for the summer.
"I'm going back home this summer," he told Inside United. "I play beach volleyball there. I like it and I have (facilities) at my home now as well.
"I love to play it with my friends. I will stay there for all the summer so it's nice to be with my friends. It's very enjoyable.
"You know what I miss most? When I go back, I always like Fridays when I have an old friend around and we play football and have a barbeque after that.
"I miss that, you know, because it's good. We have music too. We bring some guys to play songs like samba -- I enjoy that a lot.
"It relaxes me back there. Sometimes you have to do these things. It's a hard season so, when I go on holiday, I want to relax with my friends and family."
