Whilst Red Star are seen as the whipping boys of Group C, Klopp stressed that his side would not treat the game with complacency, warning his players to be ready for a ‘really hard fight’.
“I know that they are able to defend and able to create as well,” he explained.
“Different possibilities to lineup, different strikers—tall, quick—good footballers, good headers, full-backs are really leggy, on their bikes and quick, very offensive-orientated.
“They have a clear structure, so that’s what they can do offensively, and defensively, Serbian teams are always well organised.
“They know to defend, they are not bothered to be a bit more aggressive, so we need to be ready for a really hard fight, we need to fight for each little square-metre of space with all we have.
“For that we need our crowd, that’s very important. Atmosphere can make the difference and that’s what we have to make sure again.”
