Manchester United are set to offer Everton a deal worth £25 million for Marouane Fellaini's signature, reports the Mirror Everton boss Roberto Martinez has already rejected a double-bid for the Belgian midfielder and prolific defender Leighton Baines, but Moyes is now thought to want just Fellaini, and a £20 million offer plus add-on's is on the cards. 25-year-old Maroane Fellaini has made 140 league appearances, and scored 25 league goals for the Toffees since joining them from Sandard Liege in 2008 for a reported £15 million, an Everton club record. He has 42 international caps for Belgium, scoring 7 goals, and would represent the first major signing of the summer for Manchester United, with less than a week left on the transfer market. However, Everton may be unwilling to sell to the champions, who have their former manager David Moyes at the helm, and it may take a fee closer to £30 million to prise the Belgian away from Goodison Park. Whether United are prepared to pay that much for the defensive midfielder remains to be seen. There's also the World Cup coming up next year in Brazil, and with Belgium 3 points clear with 3 matches to play in their qualifying group, Everton are as aware as anyone that the competition could mean a vastly elevated sale value for their star midfielder.
