Unbelievable, 2-0.
I believe it was also a goal for Italy. You couldn't see the ball itself, but you could see that the player that kicked it out had his right leg behind the goalline and even when he kicked the ball, his leg didn't cross the line into the field again.
The ball is pretty wide - I think that Slovakian player would have had to have been another step deeper in the goal for it to have scored. Not that the AR could have seen that from where he was; you can't even tell for sure from the video. Maybe some industrious person will edit the ball in so we can take a look at it. I think that one is going to be debated for a long time.
[EDIT]: I also disagree with the linesman, that Italy goal wasn't offside.
They showed a slow-mo with the offside line drawn in, and the Italian player was clearly off. Very excellent call. Those English refs really put on a show of how to do it right.
