Our situation is absolutely nothing like United's. Our first choice right back from the Irish League who cost less than a week's worth of Fellaini's wages. If you are receiving large fees for good players, it means you have been buying good players. The only reason we have a net spend at all is because Moyes is boss at spotting a player. The fact our net spend is so low under Moyes speaks volumes about the conditions he's been under, as he's excellent at getting players to perform and then make a profit on them.
Or you're selling to city and liverpool. See milner, barry, henderson, downing, sinclair, allen etc.
