Having seen the replays, I don't think either were penalties. The angles I saw of the Brown incident showed the ball hit his torso, and the ref wasn't in a good position to award anything. There is a problem witi refs not giving much to opponents at the big stadiums especially Old Trafford. The reason for Tottenham's frustration is that they were alot better than Man Utd, but as happens so often in football, the better team lost.
Had to laugh when the Spurs fans started chanting 'You're just a shit Gareth Bale' to Giggs. Aswell as 'You're just a shit Maradona' to Tevez.
