But the fact remains that when the ball was played in the first instance he's offside. The reaction from every player on the pitch, the lineman, the commentators, all knew it was offside., then suddenly it wasn't. Bad mistake yes but offside is offside. We've seen it a thousand times when goals are disallowed because they were offside in an earlier phase of play, now suddenly they're not.So if the rules don't favor us you don't like the rules? He was in an onside position when Guehi made the horrible error.
If it was us given the goal in the same exact circumstance us attacking you'd be 100% okay with it.
