He was but Otamendi also had hold of the front of Shawcross the whole time too. Shawcross got caught, his own fault and something he's got away with for years.
Refs should give every single penalty for shirt pulling if they see it.
It was a pen, but it annoys me how much a sides status gets them those kind of decisions. Stoke wouldnt get that decision the opposite way imo. I'm still annoyed about their offside goal last season & Tiote's dissallowed goal.
As shown by the failure to give Stoke that pen. Mike Dean is the most bent cunt going.
