If the numbers are right then this is not just insulting to us as a club, it's derogatory to the players involved. In addition, Fellaini already knows he's Moyes 3rd/4th choice for his new midfielder after the other enquiries/bids they've made.
Moyes clearly has both players on his wish list - and who can blame him - and it's his new club's job to try to get them for him, but however hands-off he claims to be when it comes to bidding for them he will be all too aware of how those low-ball offers will be viewed at his old club.
Interestingly, from speaking to and reading supporters of other clubs, it's not just us who thinks £28m is insulting. I haven't had one person yet saying that we should accept the offer.
Personally, I wouldn't even consider the deal for less than £40m.
