Have finally put my finger on it, and it makes me uncomfortable.
Sure, Yaya's stamina has previously been called in to question.
But stupid as I sound, he is part of the problem.
We are a one man midfield with Fernandinho, who I thought was very good today.
Lazy rakish passing from Yaya, far too cool for school at times.
He is easily taken out of the equation when the passing is quick one-touch around him.
Everton did it to him a couple times and no surprise it becomes more pronounced against the likes of Bayern and Dortmund.
He was clearly tired from the other night, but there were a number of occasions when he failed or simply refused to close the distance between himself and numerous Negredo knock downs.
Love Yaya in full flow, his momentous goals, but he increasingly appears to be as much of the problem as the solution.
Great effort from City today. Real desire and some lovely interplay.
Silva and Negredo were fantastic and Kolarov continues to seize his chances.
