He is not nicknamed 'The Wall' for nothing but, having taken on opening, he may have exposed himself slightly. The new ball can get him out and he tends to play with his bat outside his body to a ball on line with off stump, which can result in an edge. He offers chances early on and they need to be held. For a player of his ability he tends to lose patience against spin.
