Neymar bagged a hat-trick and Kylian Mbappe netted a brace as Paris Saint-Germain topped Champions League Group H with a 5-1 home victory over Istanbul Basaksehir on Wednesday, a day after the game was suspended amid an alleged racist incident.

The PSG and Basaksehir players, as well as the three field referees, took a knee before kickoff one day after both teams walked off in protest after the Turkish side had accused the assistant referee of using a racist word against their assistant coach Pierre Webo.

The incident was sparked when Webo was shown a red card for protesting against a refereeing decision and the Turkish side then alleged that the Romanian fourth official Sebastian Coltescu used a racist term towards the Cameroonian.

Webo, who had been sent off, had his red card suspended pending a Uefa investigation into the incident and the Cameroonian sat on the bench with the rest of the team’s staff.
