Liverpool manager Jurgen Klopp says he warned his players against complacency during last night's win against Southampton in the League Cup.
The Reds produced one of their best performances of the season to set up a League Cup semi-final tie against Stoke.
And the German was visibly delighted with what he saw at the St Mary's Stadium.
"We had some problems in the first minute, no fewer problems in the next 10 and then we started playing the game, but it was not easy," Klopp said.
"For the first situation [Mane goal], we showed it to the players at half-time because if you start like this then you need too much luck to come back in the game.
"In that situation, everything that we did was wrong and only at the last, when the header was in, everybody could see and think, 'What is Alberto Moreno doing here?', but I could see 25 faults before.
"The style of Southampton tonight was very, very clear – long balls with [Graziano] Pelle fighting for them – and in the first 10 minutes they were better and getting the second balls. They were always dangerous for us.
"Then we started to play the game. Daniel's first goal was not too bad – it was a perfect pass from Joe Allen, a really, really good pass and I think it was a goal the moment the ball was in the air before Daniel got it. It was a perfect goal.
"The second goal came from a perfect pass from Emre Can and then the third goal, a good shot from Alberto Moreno and I don't know with which part of his body, but Divock got his first goal.
"We spoke at half-time and I don't like to say too often, 'it's 3-1…be careful', but always in a cup game you cannot ignore that because it's not over unless you stay in the game, stay concentrated and start better than we did in the first half – and that's what we did.
"We made super goals, I have to say – they were really, really nice with good play and good chances.
"We had to react a little bit with [Southampton's] new system, I think they went to 3-5-2 in the second half, but when we could bring Jordon Ibe on, it was a good moment for us because one-on-one, it is not easy against Jordon.
"We have to defend well and then we can use his pace, and that's what we did with the next two goals – and it was a perfect cross from young Brad Smith [for the sixth goal].
"It is not too often we can talk about this…maybe we will have to wait too long for the next time we can enjoy a football game like this, apart from 20-25 minutes. It was a good one tonight."
