I'd never want a player to get seriously injured, but when the likes of Goofy earned so much through diving and feigning injury, one cannot but smile about the poetic justice when he did get hurt.
And the thing is in derby matches, any iffy tackle is likely to be cheered given the situation.
I used to go up to Celtic-Rangers games back when Dogleash was a Celt and you would not believe how the fans used to bay for the opposition to get clattered and injured. SFA Cup Final, with over 90,000 in Hampden and the green half cheered their heads off to a man as Danny McGrain absolutely combine-harvester tackled the Rangers right winger whose name I forget.
