Thing is, with James in there that's a genuine world class playmaker in the final third. And he'll drop back, whether playing as a 10 or wide, or out into a free bit of space to get on the ball.
Doucoure's runs forward - he made more runs into the area than any midfielder in Europe's top 5 leagues last year - will add another outlet, so we don't have to worry about Doucoure having to 'create' as such.
I mean, if Gylfi stays, even he'll have that bit more space because he's not having to do two jobs (if he plays, which knowing our injury luck he'd probs have to).
