Bloody hell, OUCH!
And there's another one Ialways comes to mind when ever I see Keane - against Swindon (I think) when he tackled some one then stamped on their chest after. Easily my least favourite player ever, I think.Definitely a red but never the worst ever. For me Roy Keanes one on that bloke was the worst, pure scum, went out to end his career. I mean it might not look the worst but the fact he did that deliberately to end his career.
And this one he only got a yellow for :
Roy Keane tackle on Neil Pointon
