So, was it a pen? The Dipper-loving BBC think it was:
Man Utd goal: They hardly deserve it, but that's what champions do better than anyone else. Ryan Giggs' pass into the Arsenal box is touched on by Wayne Rooney, before a sliding Manuel Almunia takes the striker out. No complaints, definite penalty, and a yellow for the keeper. Rooney picks himself up to slot in the spot-kick. Game on.
