Bernado Silva is a fucking cheat.
As has been said Silva had been running into and pushing Sa all game, but the ref team didn't do anything about it.
For their second goal he backed into Sa, impacting him considerably, and IMO that threw Sa off balance and obviously taking his concentration away from the game. Offside is not the issue, it was interfering with the goalkeeper.
I'm amazed there seems to be no photo of it.
Bernado Silva is a fucking cheat, and thanks to the officials, he unbelievably got away with it.
