Sorry, i mean in a defensive position this season he has been surrounded in the majority by Sagna, Kolarov, Clichy, Otamendi, Demichellis, Mangala, Delph, Fernando and Fernandinho. This is the area of the pitch that he has to drop into because none of the above are good enough with the ball to allow us to play possession football from the back. The technical ability is at the other end of the pitch, but even then, Silva has struggled badly this season, Sterling doesn't really have a reliable touch, De Bruyne and Nasri have missed big chunks, Navas is ridiculously one-footed.
I don't get why you are so bothered about him ambling around for 2-3 seconds after we lose the ball. So does Aguero, so does Silva, so does De Bruyne, so does Nasri. The only attacking minded players who don't are probably Sterling and Navas and the only reason they get on their bike is because they have an opposing full back to track. So long as Toure doesn't allow the opposing centre back or defensive midfielder to amble past him, it's irrelevant and it is such a ridiculous point to attack him on.
I could totally understand your dislike of him if we had better options in the squad, but we quite clearly don't - as Liverpool away and Norwich away have recently shown.
