Finally somebody on the thread who talks sense!, Well done that man...

So when the ball is kicked in the air, as long as the player is looking at the ball, he can shove the player out the way? Just because hes not looking at the man doesn't mean he can push him out the way and doesn't no were he is. That was the correct decision.

You are the sort of person they employ as a video ref clearly! They should have recent former players in the video ref box, or just bin them completely. Clarke went towards the corner flag, without touching anyone, and Diskin followed him and tackled him. How is this an obstruction when the defender chooses to follow the attacker in a direction away from the ball? Please explain..?

No, the defender CHOSE to follow the attacker and tackled him without the ball, not the other way round, its such a simple concept!. This is the best example of a dummy run you'll see, but people without a bloody clue can't see it.

buchanan ran into him end off. penalty
