Yes, I'm sure Khazri will do brilliantly. He had a very high whoscored rating, which corresponds very well with scores in this game. 'Chances created' is a big difference maker in scores, even if they aren't converted into goals (this is why Eriksen is so brilliant) and Khazri is very much a creator. I only left him on the bench because I wasn't sure if Fat Sam was starting him yet - now it looks like he is, I think he'll be in my team most weeks (although they do have some tough fixtures at the moment).
EDIT: On Imbula, my general impressions are twofold, a] that Stoke are shit right now anyway, and b] I don't think midfielders score as high if they play in the double-pivot.
