That's what id go with as well but think he will shoe horn Yaya in.
KdB plays centrally again we win the game its that simple imo.
I suspect you're probably right. I'd far rather have Yaya as an option to come on for the last 20-30 minutes as needed, but I expect him to start.
If he does go with Toure, I hope he tweaks it slightly so as to play a more orthodox three in midfield (à la Seville). Wouldn't be keen on seeing him as a 'No. 10'.
I suppose the other option would be to go back to using Fernandinho from the right? Fernando and Yaya in the middle, Silva on the left, De Bruyne up top with/just behind Aguero. Again, not convinced though.
