Thanks for the freeze-frame; I posted a few pages back, just after the full-time whistle, how laughably offside he was. It wasn't even one of those where you needed a screen grab, in fairness - he was fecking miles clear, and the gap looked even bigger at full speed.
Ok, they f**ked it up and didn't score, and it is therefore a moot point, but as you say, that sort of stuff can't go for one side and not for another (I'd say the gap is about the same as the one for McGregor's disallowed goal.) Yes, both miles offside, but only one decision was given correctly.
