Weird sense of entitlement among some of our fans.
Ajax have every right to rinse us, and they have every right to not be all that enthusiastic about selling a player that they put in the hard yards to scout and develop that they haven't really got full value from in sporting terms - he's only played 50 odd matches.
All these notions of it being bad for them to do it because it gives them a poor reputation, or players will be less keen, or that they're destroying dreams are complete one eyed, United tinted nonsense.
