I'd sign him up just for that.. we need Baines back to his best and if a little competition stirs him up then I'm all for it, watching some of last years highlights shows just how flat he's been for most of this season.
However, Knut could turn out to be good himself.
Not much turns up on the youtube about Knut, just a polar bear, 1 fan video where he donates his shirt and this bloke.
