I generally find it's an odd 5-1 win where the winning team didn't deserve to win XD

As for two team-mates fighting each other, I remember David Batty and Graeme Le Saux for Blackburn in a European Cup match back in 95/96.

And yes Wembley is horribly jinxed so far for us: first Man Utd v Chelsea, now Chelsea v Spurs!
