The Agger headlock was worse than you normally see but pushing, pulling etc from corners goes on all the time and very rarely is anything given. The Shelvey one was ridiculous though; even if he couldn't see the penalty, he should have pulled it back for the free-kick for the pull on him just outside the box.
The worst thing was Probert was indicating advantage for the foul outside the box, then once he thought west ham had 'won' the ball, he just said no penalty, literally the most inept referee I've ever seen.
I remember last year vs Bolton when we won 3-0 there was a backpass to their keeper (now the hammers keeper), like as blatant as they come and he just let it go.
Guy needs to sort out his posture as well, going to have a **** back later in life.
