Biggest Yaya backer on the board, and I thought he played well on Tuesday, but from the praises coming to him I think majority on this board don't understand his main role on the team. On Tuesday team was playing behind the ball, and counter attacking which they don't do 99% of the time (mostly possession based team). Yaya role was to play behind Aguero and spearhead the counter attack. He did that well, but for all the praises coming to him for he wasn't that effective in the end because team didn't score. He had more sprints and more action in the final 3rd giving the appearance of effectiveness, but I don't think there were that many clear cut chances.
Majority of the time Yaya is initiating the play from deep and linking D to forwards. So if all is going to plan, he is laying the ball at the feet of the likes of Silva, Sterling, etc to make the final move to Aguero. He is not going to get credit if it comes off. If team is chasing goals, he will go forward more often and take more risks, and it will appear like "he is trying harder" but really he is playing a different role. Most fans don't recognize this and slag him with lazy tag.
