Just re-watche dit on MotD. Bellamy should have got a straight red, no question. He's sprinting full pace, pumping his arms in a repetitive motion at a certain height; when he sees Baines is clearly going to overtake him, he suddenly raises his left arm much higher and swings it back sharply, making contact with the elbow and barely missing with the fist - Savage and Owen both noted the clenched fist. Martinez should send the footage to the FA and demand action.
The Korean lad's effort was less dramatic, but was still a clear elbow jabbed straight at Pienaar's throat. Two definite red cards. For balance however, Felli could have seen red for his ground and pound effort, but you have to feel that perhaps if the ref got a grip of the game at some point, two of these incidents might never have taken place.
And the pen was clear as the nose on my face. Not a single pundit or commentator has said otherwise on Setanta, AL Jazeera or MotD. Even Michael Owen saw it as a pen.
