The tackle didn't end Haaland's career, he actually played in the match after that game, but came off. It was a long standing injury in his left knee, (Keane's challenge was on the right knee) that ended his career. Of course Keane is an idiot, and deserved the mockery, after it was him that attempted to injure Haaland in the first place when he was at Leeds, and ended up getting injured himself. As for Keane's apparant "hardness" don't make me laugh. The guy is a fake thug, a playground bully type, who picks on the easy targets. Dirty challenges, and cynical stamps when the referee isn't looking, doesn't make you hard at all, unless your 14 years old, or an old fart who longs for the 'good old days' when players could tackle from behind and get away with it, and moans that the games gone soft, and idiots like Keane are some kind of beacon, because they put in dirty challenges and shout, a nostalgic reminder of the days when players were supposedly hard, because they wore short sleeves, and could put in disgraceful tackles legitimately. Keane would never dream of starting on someone like Duncan Ferguson, Julian Dicks, or Tomas Repka.
