Liverpool boss Jurgen Klopp says he and his team felt they were only "average" on Saturday as they beat Huddersfield Town 1-0 and he is hoping to see a significant improvement from them when they host Red Star Belgrade on Wednesday.
The Reds ground out an away win at the John Smith's Stadium to keep level with Manchester City in the Premier League title race, but they will switch their attention to the UEFA Champions League for Red Star's visit.
Liverpool are yet to sweep teams aside in the convincing manner they did last season and, while Klopp conceded that it's difficult to maintain that level, he is hoping to see more from his side.
