Did Silva nudge the keeper a couple seconds before the header? Yeah, a little bit.. But the ball literally went over his hands, it was headed right at him, and it just went by him too fast to react.
We're clutching at straws on this one. Regardless if we had one rules out for White, I would see that as a legit goal all day long. Silva was a yard to the right of the keeper when the ball was headed. Could not see any way VAR did not rule that as a goal.
