The problem is that for all the stick Toure gets, he had the best pass completion of any of our midfield players; Manga, Sergio and his brother(!) were the only players in the game to have better pass completion. No one on the Dippers team made more passes than Yaya and only four City players did, even though he only played one half, and then by no more than 7 passes. He also made as many tackles and interceptions as Dinho. So whilst he did stroll too much, he did not lack for involvement in the game or quality.
I think to accommodate Yaya now, we should move to a proper 4-3-3: he isn't a number ten.
