Sorensen's looking a bit shaky, but the main issue is he's being beaten for pace consistently, so he automatically finds himself in a scenario where he's gonna make either a rash challenge or a mistake.
You can see Motta warming up for this reason...which might as well be a worse choice, to be honest.
Aquilani isn't concentrating at all.
Iaquinta, for once in his life, is being totally unselfish. It's paying off.
