Liverpool boss Jurgen Klopp took aim at Anfield fans last night after their Carabao Cup quarterfinal win against West Ham.

Klopp concedes the atmosphere has been lacking in recent games.

He snapped: "In the first half, when the boys played exceptionally, I was not overly happy with the atmosphere behind me.

"I asked people: 'What do they want?' We changed a lot of things and we dominated West Ham like crazy and missed chances. If I was in the stands, I would be on my toes, 1,000%.

"I don't know if the Man United game was that bad that we have to say sorry we didn't smash them?

"We need Anfield on Saturday.

"Arsenal didn't play this week, they prepared for this game and anyone who knows anything about them knows they will be prepared. So we need Anfield on their toes from the first second, without me having an argument with the opposition coach or whatever. We need you from the first second.

"If it is too much football in December, I'm sorry, we have to play as well. If you are not in the right shape, give your ticket to somebody else. It was not negativity, it was just not the excitement I felt the performance deserved. There were so many good performances but we were only 1-0 up.

"We had so many challenges to be celebrated and we had a lot of chances but if it is the warming up for Saturday then I am happy."
