I came on this thread to show how Silva was *definitely* offside, and I have to say I am surprised.
He is in fact offside, but it is much closer than I thought. And taking this "when did Fernandino actually play the ball" question into account, it varies from *just* off, to quite clearly off, depending on whether you go for the moment of first contact with Ferna's boot, or a tiny bit later than that. Either which way, Silva was off.
This is *before* Fernandino kicks the ball. Silva is on, but Ferna hasn't touched the ball yet. You can just make out his right boot peaking out from behind his left leg as he prepares to play the ball.
This is the first point Ferna touches the ball. Notice the ball has not moved yet. Silva is already (very marginally) off.
This is the point the ball clearly moves. Silva is even further off.
And finally, this is the point they choose to freeze the frame. The ball has long departed from Ferna's boot, and of course Silva is even more off by then.
The point though, is it was mighty close. A travesty of a refereeing decision, it was NOT.
