The newcastle penalty was blantant, he did not go down well after the contact, his left foot is clearly blocked, his right foot planted as it wasn't impeded, it was the next step he went down because his left foot being hooked stopped him continueing, stone wall penalty, clearly not a red card.
Hernandez both, jumps in the air, makes no or minimal contact, his foot hit the floor behind Simpsons, it wasn't prevented from doing anything, then he threw himself in the air. What I always find pretty obvious is, when a player jumps, then acts like both legs were hacked down, he's cheated.
You're also forgetting about the ridiculous Vidic elbow/head where he threw himself across the box, smashed into Ameobi, got none of the ball and absolutely destroyed Ameobi, that should also have been a penalty. Vidic then also threw another elbow at Ranger.
The Tiote one, it hit his arm, his arm was out but still to his side, he was side on to the goal, if it didn't hit his arm it would have hit the side of his body anyway, no penalty but its the closest Utd got to a real penalty claim.
Newcastle were great the first half, miserable in general in the second, Utd the opposite, appauling in the first half, you really very rarely see Utd under that much sustained pressure.
Carrick was rubbish again, Anderson did smeg all, Giggs was fouling quite a lot though one of the fouls against him was Barton just flopping in a good freekick position.
