Jürgen Klopp has declared himself 'absolutely not happy' with Liverpool's season so far, insisting he will only be able to reflect positively on what his team has achieved come the end of the campaign.

The Reds took a huge step toward qualification for the Champions League quarter-finals last week as they carved out a 5-0 aggregate lead over Porto in the first leg of the sides' last-16 tie.

Things also look promising on the domestic front, with Klopp's men sitting third in the Premier League - just two points short of second - ahead of Saturday's meeting with West Ham United at Anfield.

But the German isn't satisfied yet, with his sights set firmly on the challenges that lay ahead.

Klopp told reporters: "I am absolutely not happy. I want to be happy at the end of the season. Happy is not the word I have in my mind, to be honest; I am sometimes fine with it, sometimes more, sometimes less.

"Immediately after the game against Porto, it is not good for me as a human being, but I thought about West Ham - that is our life, to deal with that.

"What I want is that we are really ready for this game tomorrow. They will defend a little bit deeper, probably, and we need an atmosphere that is ready for that as well.

"It's nothing decided this season, we are in a good position but a good position only gives you the basis for the next few games and now we have to use it as a group - players, coaches, manager and crowd.

"We need to be ready for a difficult game tomorrow because they - I don't know exactly the results but - drew against Tottenham, lost with one goal at [Manchester] City, stuff like that. It shows you need to do it.

"They always have opportunities with counter-attacks and set-pieces to score by themselves.

"Either way, it’s all negative or when it's positive it's so positive that we don't care about the next thing. I am not like this.

"I really want to use this basis now and, for that, we have to be at our best tomorrow afternoon, so I know it’s a lot of work to do."
