From my position in the East stand, you could clearly see that Pep was getting annoyed with him and his positioning on the pitch. He obviously wasn't following his instructions closely enough and Pep was turning to the bench and gesturing every time the ball came out of Arsenal's defence.
He definitely had a brain fart when we passed it back to Cech though.
I think he was trying to play it off the defender and out for a corner but the defender was a bit too cute for him.
