Liverpool boss Jurgen Klopp has told any supporter "not in the right shape" for Saturday's top-of-the-table Premier League encounter with leaders Arsenal to give their ticket to someone else.
Klopp - whose side are a point behind the Gunners - criticised the Anfield atmosphere during Wednesday's 5-1 Carabao Cup quarter-final win over West Ham.
The Reds galloped to their joint-biggest win of the season to book a two-legged last-four encounter with Fulham.
Yet, despite goals for his side from Dominik Szoboszlai, Cody Gakpo, Mohamed Salah and Curtis Jones, who scored twice, Klopp felt the atmosphere inside the stadium was flat.
