The Toffees are close to completing a £8.6m deal for the Dutch star, although the midfielder’s move is now in doubt after Everton unearthed a knee injury during his medical.
The Merseyside outfit want to renegotiate the deal in order to protect themselves financially should the injury reoccur after Fer was side-lined with the knee problem for much of the 2011/12 campaign.
Chelsea have been heavily linked with a move for Fellaini, who has scored eight goals in 22 appearances, in recent months, but Moyes insists the Belgian won’t be leaving despite Fer’s touted move.
“I read something about him replacing Fellaini and that’s the biggest load of tosh I have heard,” Moyes told the Mirror.
“That’s nonsense, whoever wrote or said that.
“They are different types of players. No, that’s not the reason for bringing him, that’s for sure.”
