It ws 8 years ago, let it go man. And he did many great things for us (Man United) which mattered the most.
Oh and Michael Owen said he went out to delibrately injure a Man United player in 1998, he got sent off in that game for a dreadful foul on Ronny Johnsen, any action taken? Didn't think so.
Oh and the Ireland fans weren't mad at Keane, he went back to Ireland 2 months later for a pre season friendly and the applause he received blew the roof off.
