Roberto Martinez won't sell Marouane Fellaini to Manchester United

MANCHESTER UNITED face a mighty battle to get Marouane Fellaini insists Everton boss Roberto Martinez.

There have been no official bids yet for the big Belgian

The Belgian ace is wanted by former chief David Moyes and would fancy a move to Old Trafford. But a clause allowing him to move for £23.5m expired at the start of this month, so Everton will now play hard ball in a bid to keep their star man on Merseyside.

Moyes, who signed Fellaini for £15m from Standard Liege in 2008, is desperate to bag him again after failing to lure Cesc Fabregas from Barcelona.

United have yet to make an official bid, but the player's advisors are fully aware of their interest and want to strike a deal.

Everton boss Martinez thinks he can get him to stay at Goodison Park, though.

He said: "I said from day one, as a manager you only concentrate on day to day and working hard.

"I don't mind players grabbing headlines. That's a good story. That means they've been doing well and are outstanding performers.

"I know that Marouane and Leighton Baines have been working very hard for the team. And that is all that matters.

"There has been no bid."

Fellaini struggled with the intense Miami humidity along with the rest of his Everton pals after they crashed to a 1-0 defeat against Valenica in the final game of their US tour.
