Manchester United are reportedly planning a fresh £20m move for Everton midfielder Marouane Fellaini and are keen to sign him before Sunday's match against archrivals Liverpool at Anfield.

The Red Devils had failed with a combined bid of £28m bid for Fellaini and left-back Leighton Baines last week, with the Toffees labeling the valuation as "derisory and insulting". Reports suggested David Moyes would return with an improved offer for the duo but, according to the Telegraph, the Scot has now decided to focus his efforts on landing just the Belgium international.

The report also states United's new bid for Fellaini will be in the region of £20m but the Mirror claims the offer could go up to £25m and will be made in the next 24 hours. The 25-year-old is understood to be very interested in a move to Old Trafford and a reunion with his former manager Moyes.

Fellaini made 31 Premier League appearances for Everton last season and notched 11 goals and five assists, operating in a more advanced role. The player, who arrived from Standard Liege in 2011 for an initial fee of £15m, had a £23m release clause in his Toffees contract but it expired at the end of last month.

Everton are determined to not sell Fellaini, if United do not match their valuation for the player. However, the reports say Roberto Martinez has already identified Wigan Athletic midfielder James McCarthy as a potential replacement, should the Red Devils make a significant offer for the Belgian.

Martinez had also revealed there have been no fresh approaches from for any of his players this week, though he is well aware that United could be weighing up their second offer.

"Nothing. I know there's going to be talk about the transfer window but that's not what we're focusing on now when we've got an important game in front of us," the Spaniard said.

The Toffees will host League One side Stevenage in the second round of the Capital One Cup on Tuesday.
