I doubt ManU went into the game confident that Riley would cheat for them, however in the back of their minds they also knew what his record was for them.
The key point in the match was probably the Cole yellow. The Munichs had just spent about 10-15 minutes kicking Reyes off the park and G Neville probably should have seen red at that point, yet they hadn't received a card of any kind. At that point Cole commits a slightly cynical, non-violent foul and gets a yellow.
I'm guessing that at that point they all thought to themselves 'game on - this is 12 v 11' and then proceeded to act accordingly over the rest of the game.
But shouldn't we move on? No one was angrier than I, no one remains as bitter and twisted as I (well, maybe IUFG) but surely we should get over this? I mean, it really isn't healthy.
