The Champions League game between Paris Saint-Germain and Istanbul Basaksehir has been abandoned after a match official was accused of using racist terms on one of the French giants backroom staff.

Istanbul allege fourth official Sebastian Coltescu used a racist term towards assistant coach Pierre Webo.

Former Cameroon international Webo was shown a red card in an exchange on the touchline.

Istanbul players walked off the pitch in protest with PSG players following.

The incident happened just 14 minutes into the Champions League Group H tie, which was still goalless.

Istanbul forward Demba Ba, who was a substitute, could be seen on the touchline asking the official: “Why, when you mention a black guy, do you have to say this black guy?”

The match is set to resume with a different fourth official.

In a statement, Uefa said: “Following an alleged incident involving the fourth official, the match was temporarily suspended. After consultation with both teams, it was agreed that the match would restart with a different fourth official.

“Uefa will thoroughly investigate the matter and further communication will be made in due course.”
