Manchester United will test Everton's resolve with a renewed bid of £20million for want-away midfielder Marouane Fellaini, according to the Daily Telegraph.
The 25-year-old has been heavily linked with a Goodison Park exit this summer, with the Premier League champions touted as his most likely destination.
New Red Devils boss David Moyes is keen to be reunited with Fellaini and Leighton Baines, but has so far failed in his pursuit to bring the Toffees duo to Old Trafford.
A combined bid of £28million was deemed "derisory and insulting" by the Merseyside club, and now Manchester United will focus their attention solely on signing the Belgium international.
Fellaini actually used to have a £23million release clause written into his contract, but those terms expired at the end of last month.
However, the midfielder has made his desire to join Manchester United clear, as he looks to fulfil his ambition of playing in the Champions League.
Moyes will have to move quickly if he is to secure Fellaini's signature before the close of the transfer window next week.
But, with an improved bid anticipated, Everton boss Roberto Martinez has already lined up Wigan Athletic's James McCarthy as a potential replacement for the Manchester United-bound star.
