I'm hoping to go for a better creative force than sigurdsson personally. He was a big fish in a small pond, doesn't mean he can make step up.
He's also like, 22, which means if he's going to step up now's the time. Could be a good signing, but I can't see it right now given the presence of Aquilani, Shelvey, Henderson, Adam, and Cole in that role (not that I think too many of those are superior players).
