Jurgen Klopp has revealed he was angry at half-time at The Etihad - not because of Sadio Mane's red card, or because his side trailed 2-0 - but because his Liverpool team was only performing at 60-70 per cent and might have won had they been playing at 100 per cent efficiency.

And the Liverpool boss wants his players to learn from the chastening experience.

"We have a lot of things to learn from this game," he told liverpoolfc.com.

"I was really angry at half-time. Not angry because of the result but because the boys saw we could have won at 100 per cent.

"It's not important any more, we lost 5-0, it sounds crazy I know! The first half, we didn't play like we wanted to, we were 60-70 per cent."

Klopp doesn't know why his side failed to hit 100 per cent intensity but believes the international break, with so many players making long journeys back to Merseyside, might have played a part

"Sometimes it's impossible after the international break - different plans, different positions, they played all over the world, I don't like this but we cannot change it - but you saw City struggled also a little bit," he added.

"We had then these clear moments and then it's one goal conceded, forget it, it can happen, but the red card gave them the advantage.

"Everybody knows it's a bad place to be one man down and we could see this so we tried to drop a little bit deeper, but it makes completely no sense.

"We have a lot of things to learn from today, but the problem is today we cannot change it, we can only learn from it and make the next time better."
