Jurgen Klopp and Pep Guardiola have been told they must not cross the line when Liverpool and Manchester City clash at the Etihad on Thursday night.
The animosity between Liverpool and City hit a new low earlier this season when the Blues allege coins were thrown at Guardiola and there was offensive chanting and graffiti about Hillsborough.
Klopp also landed a touchline ban for losing his cool with an official and his No.2 Pep Lijnders says they know they need to keep their emotions in check. Lijnders faced the media instead of Klopp at Liverpool’s press conference on Wednesday and said the team that wins is the side that keeps their cool.
