AgreedSpot on and I've no idea why! Nacho has shown a desire to drop deeper to pick up the ball, and though Aguero likes to do that as well all it takes is communication to day - one of you push forward and make runs in behind. The two of them would work a lot better than Bony and Aguero. They just don't have a relationship and Bony has done nothing and continues to show a lack of ability/confidence to perform for City unfortunately. Pellegrini though continues to swap Aguero for Nacho and bring on Bony to support him. It's predictable and it doesn't work.
It would seem he would put the kid in just to TRY SOMETHING DIFFERENT if for no other reason
