There are no agreements in place preventing David Moyes from returning to Everton to sign players for his Manchester United squad this summer.
The Mail on Sunday says Moyes will be free to make bids for any Everton players when he joins United.
Marouane Fellaini has a get-out clause allowing him to leave for £23m and clubs in Russia are keen.
Leighton Baines would also interest Moyes but Everton's £15m asking price for the England defender would make a deal unlikely, particularly if Fellaini is sold.
