JC you need to lighten up man.
When players leave clubs there are always fans that will call them tata etc. thats the way fans are. KJ lost an awful lot of respect by the fans when he said if we went down he would leave just a couple of days before a vital last game, why only he knows but never the brightest move.
As for Bent its not that he left, more what he said and the way he left he is always going to get abuse. He went out of his way quite regularly going on about how much he loved the club, supporters, area etc. Nobody made him say it, he could of just been like the rest and kept his head down and said little. He went to a hotel in Brum without permission and made it clear he wasn't coming back, then made out he left for football reasons, when Villa were in danger of relegation. Him and him alone put himself in that position he took the plaudits and enjoyed them, he has to take the consequences.
It would be like me telling you how great you are, best friends, love you and never leave you, to buy me beer in the bar all night. Then someone else comes into the bar that will buy me Champagne I just bugger off and start telling them you can peel an orange in your pocket because you "only bought me beer" and never appreciated me and would never be any good for me if I stayed with you. Don't think you would be too happy, that is what basically Bent done to them in the fans eyes.
As always with these things there is very rarely just one side although people tend to pick them.
