Think the ref got the two penalty calls spot on.
Sure, the Stoke player was close to Bendtner, but you do an impersonation of a scarecrow and the ball hits your arm, it's a pen.
The second one was shoulder to shoulder and the Stoke player was stronger.
Worst thing about this is that Arsenal will be bleating about their mental strength. They don't actually have it, but something like this might help them get some.
