I sort of agree with that. When we brought Gelhart and Lang on the Burnley central defenders afternoon became a little tricky for them and they started to panic a little bit. Perhaps Cook needs to think about that, the shape at the start of the second half seemed like a 3-5-2, which easily became a 4-4-2 or even a 5-3-2 when Burnley exerted a little pressure. But having had a really comfortable first half against the lone threat of Garner, I thought they looked a little questionable against two young upstarts who were harrying them!
I also thought that for the brief spell that Cook used da Silva Lopes as a wing back he looked like he could be a handful too!
