The above has a lot of myths attached to it, even John Motson patronising comments are completely wrong.
Zaire qualified on merit ahead of Morocco, they were also ACN champions at the time.
Backdrop to this was Zaire was under the dictatorship of Mobutu at the time.
Zaire played Scotland first and lost 2-0 but caused Scotland a lot of nervy moments.
Mobutu was heavily pissed off tho all the funds that had been put aside for players whilst in Germany vanished. They initially refused to play Yugoslavia in the second due to this only because of threats to family back home did they play but were not arsed and lost 9-0.
The final game v Brazil was a dead rubber for them and they were threatened if they lost more than 3-0.
They lost by that scoreline, the player who kicked the ball away Ilunga Mwepo was very vocal in the players protest and it was believed he want to get sent off in a way of protest.
What it does is it puts the myth to bed that the Zaire players didn’t know the rules and were at the World Cup on some sort of charity qualification.
