The important detail that gif doesn't show you is Oliver's angle. What you need to realise is that he was positioned so that Milner was between him and Sterling - from that angle, it's basically impossible to tell what happened.Just found a gif: https://twitter.com/bigsoccerheadNY/status/843510384715796480
SFP or reckless at best. Or YC for Sterling's dive?
(And doesn't show why Aguero's on the ground. Two fouls in two seconds.)
