still didn't get, why did the ref disallowed Silva's goal?

Ref team needs a several match ban for being so useless. Silva goal is legit, Sane not offside on it and either way, Sane is not interfering with the goalie's ability - or lack thereof - to save the shot. How did they get it wrong after review, I cannot understand. But more importantly, because City dominates, lesser teams get a pass for trying to kick them off the field. That tackle on Sane should be a red every day. That lame excuse for a minor league player Bennett stayed on somehow, and could have severely injured Diaz on his second yellow. Is that the benchmark? Ok if you injure two players, I'll have no choice but send you off... pathetic referring again.
