To be honest, it's the worst thing I've ever seen in any context not just on a football pitch. The sheer visceral horror of it means that whenever I close my eyes I see the full ghastly scenario played out in slow motion and I'll never escape this mental rotoscope of trauma.
Now, you might well say that there are worse tackles and worse incidents on football pitches across the World on a regular basis but my own subjective reaction to this most heinous of acts, this vile desecration of the sacred brotherhood of humanity, makes all these objectively worse and regular incidents pale into insignificance. We all know that this career ending tackle, irrespective of the fact that it wasn't a career ending tackle, is the single worst incident in the history of the sport of football ever and it is only our one eyed Man Utd bias that prevents us from admitting this.
Why are we even talking about Keane? It's the victims like Bernstein, who have to live with this abomination seared into their retina, and who are left with only the rending of their garments and the cold solace of alcohol as they attempt to mend the shattered remains of their lives and heal their scarred minds, that we should be thinking of.
