It's a legitimate offside, but you have to wonder about the use of VAR for it.
Gnabrys shoulder is beyond the portugeues player, but the rest of his body is level. Then for the chance, Gnabry is using his legs to go for the ball (not his shoulder) and totally misses.
The portuguese defence and keeper haven't exactly been fooled into defending an obviously off player or anything, they're continuing their job as usual.
and ultimately at the end of it, we're denied a good bit of football with the finish. is it an improvement, having VAR call offsides near the technology's margin of error like that?
