Football!

But for me personally, the peak of refereeing outrage, when a referee practically killed a team that was head and shoulders above its opponent, was the 1/8 final of the World Youth Championship (2002): South Korea vs. Spain.

And that entire championship, from a refereeing perspective, was a complete disaster. I don't remember such poor refereeing at any World Cup or European Championship. And I've seen quite a few (starting with the 1986 World Cup).

Yes, that was the height of injustice. I've also been watching football for a long time, starting with the 1982 World Cup (I remember my orange-colored jersey... :) ). But in the match against Spain, Korea played in the quarter-finals. In the 1/8 finals, they also defeated Italy with the help of the referees.

I only remember one match with a replay. It was Spartak and Basel (Switzerland). Then Spartak won with a score of 5-1 (if I'm not mistaken).

That was a replay due to the size of the goal. After the away win, a draw would have been enough for Spartak, and they achieved it. Basel was outraged. They were punished.
In the case of Lokomotiv, the replay was scheduled due to a refereeing error, something related to the sending-off of Pimenov. This was the first and so far the only precedent when a match was replayed due to a refereeing error. Previously, we were told that this never happens. And how upset we all were, the guys, when in the 1/8 final in Mexico, the referees ruined the brilliant Soviet team, which could have easily become a medalist... But they said that matches are not replayed due to refereeing errors, and then... Kaiser intervened, and they replayed the match...
The best match in Nigmatullin's career and the best match of the referee who officiated matches involving domestic clubs and national teams.
