It was a scene that brought shame upon UEFA and was responsible for both Paris Saint-Germain players and their Istanbul Basaksehir counterparts walking off of the pitch in disgust.
During the Champions League tie this week, the fourth official was accused of racism by the Turkish side.
With so much focus on kicking out racism at present, it beggars belief that an official would allow themselves to be involved in the same.
However, as Romanian journalist, Emanuel Rosu, noted on his official Twitter account, there seemed to be some confusion in his use of language.
The fall-out from the incident saw the game abandoned on the night but played the next day with an entirely different group of officials.
It’s a very delicate ongoing situation, as UEFA look to make some sense of the incident and the furore that erupted thereafter.
There every move will surely being watched with interest, and with Rosu setting out (below) exactly what was said, their conclusions could be game-changing.
