Actually I watched it with friends, and one of them said moments after it happened
"A brilliant career, all those goals, everything he's achieved, and now this is all he'll be remembered for."
Or words to that effect.
People still remember Cantona for being a brilliant player despite his kung-fu antics. So maybe Zidane wasn't all that brilliant anyway.
They also remember him (Cantona) for talking absolute bollocks (fish, trawler, seagulls etc).
and TV commercials.
