The referee who officiated the Barcelona vs PSG game Denis Aytekin has been accused of calling PSG players names.
The referee who has come under-criticism during the clash was said to have insulted the PSG players after they protested his decisions during the match.
The Catalans came from 4-0 down in the first leg to win 6-5 on aggregate at the Nou Camp, but the referee's performance in the second leg has been decried.
And according to Le Parisien, the German "showed himself to be much harder with the Parisians, insulting them with cries of “**** you”."
Despite the claims, none of the PSG player have ever said they were insulted by the referee who Uefa were believed to be considering punishing.
Reports claim UEFA are looking to demote the referee who will no longer officiate Champions League games.
