#4 Manchester City were confused during corners
Manchester City seemed vulnerable at corners, and it actually cost them three points, when Lucas Moura scored a header in the 56th minute of the game, and a few seconds later after he marched onto the pitch.

In the video above you can see nobody was looking after Moura, and he took advantage of it and made 2-3 stretches before waving himself in the air and making a beautiful finish.
Additionally, Sergio Aguero was seen not even defending the corner and could have marked him, instead they were without a man and instead probably could have saved the goal.
It is being assumed that Pep Guardiola confronted Aguero on the sideline after he was subbed off, and it turned into a heated argument.
