[Onside] The assistant referee judging a razor-thin line on a goal from a cross

Look at the assistant referee's judgement and how they kept in line. As the replay shows, it was a razor-thin decision. The replay also clearly shows the assistant referee positioned in line with the second-last opponent. Moving continuously with the line requires very quick reactions and is not easy. Keeping in line like this even in a fast-moving situation is truly excellent. It is likely that keeping in line is what allowed the assistant referee to judge such a razor-thin incident correctly. This is a valuable example for assistant referees.
