Player Valuation: £150m
You could argue the converse though Dave. As despite the fact that given the choice we'd not want to lose either player, both going would provide the manager with a hefty war chest to build his own side at Goodison, if they both stay, then his budget will no doubt be the usual pittance & so he'll find it hard to make any significant change.
If one went (Fellaini) he'd have the money he needed right there, because his task (and he's stated it) is not to revolutionise things but to get our existing players capable of adapting to different styles of play in games, and that would be his major input. He's no need to bring more than three changes to the first team and bring in a couple more squad fillers.
