Klopp said: "Very disappointed, obviously. I think everyone can see that only one team wins the game, and that is us with the chances we created, with the possession we had, with all the things we did. It was a tough one at the end of a four games in 10 days period, but I think the players did really well.
"We just conceded out of nothing and need a few more chances and kind of scrappy goals in the end to score twice. When we are 2-1 up we could control it, and still as I said in a lot of moments playing really well but the final situation we didn't take. That has been the story of the last four weeks."
On if it is unlucky for a few attackers to be out of form, he said: "It is what it is. You see the games. We are together and we go through that together, that is all. The boys want it, they fought hard, gave absolutely everything. For some of them it was definitely too hard today, and yes that's it."
On the second half reaction, he added: "Very pleased. It was very good and it was what we needed, the early goal helped obviously. We find chances always, you see in the first half we have a lot.
"What I don't understand is that with each chance we miss everyone is there throwing arms, but a chance is the closest you can get to a goal so we have to be more positive there. Accept these kind of things happen and then do it again, and again and again.
"We played well but didn't finish the situations off and now we have to acknowledge and carry on."
