I wouldn't have Silva as motm but am surprised to read anyone thought he was poor.
Off the top of my head I recall him setting Aguero up for the chance that the defender blocked after a poor first touch, put the ball in for Aguero who's rebounded effort fell to Sterling, played a lovely cushioned pass which led to the penalty, and slid one through for Aguero which he tried to toe poke in but the keeper put it out for a corner.
On another day 1 or more of them passes to Aguero leads to a goal and Silva is getting praised for setting him up.
