I see the video referee causing a bit of predictable controversy in the Confed Cup. Russia had a penalty appeal, Mexico broke away on a counter, but the ref broke off the attack to go and look at the replay of the penalty incident. He decided no penalty, and so it was a drop ball, which was uncontested as Russia just gave possession back to Mexico - as far away as possible, of course.
Game was stopped for a good 45 seconds in the meantime.
All a bit ridiculous, and would be even more farcical if in any way regular.
