Jurgen Klopp could face a ban for his criticisms of Champions League referee Szymon Marciniak.
He criticised the referee after becoming infuriated with Neymar’s antics during Liverpool’s 2-1 defeat to PSG.
“A referee needs to be prepared for a game like this and he looked not prepared,” said Klopp.
“The referee still thinks he did everything right.”
UEFA suspensions means that Klopp won’t be allowed to have any contact with his players from the moment they arrive at the stadium until after the match.
It means an anxious wait for Jurgen to see if his comments have been reported to UEFA by match delegate Eduard Dervishaj of Spain.
