Klopp said: "It was, it is so important the goal which gives you three points. It's always super-decisive and, especially for him, super-deserved. People singing that song more often, it's the best way to calm it immediately down, but they can sing it if Darwin responds like he did today. Before that he had really good moments. I think it was him after a set-piece, if I'm right, (where it was a) sensational save of the goalie. It was his chance as well. He was really immediately in the game, in a difficult game for us obviously.
"Game No.4 in 11 days is always difficult. With our squad situation, it's super-difficult. We didn't start particularly well, it was obvious, but we had no real rhythm that was the problem a little bit. Not really fluent, these kind of things, you have to play quick against a defensive block, you have to play in the right spaces, we had too many players behind the ball normal football things and created anyway then a few chances, not the biggest ones. But we had a few chances which showed us how we can do it.
"And then second half, the game gets more and more difficult, opponents fighting for the result, bring on Taiwo (Awoniyi who is) a real handful and a proper target player for counter-attacks, (Anthony) Elanga and (Callum) Hudson-Odoi around him, (Morgan) Gibbs-White now with the space there that's really tricky.
"We defended that exceptional in the last moment with the four in the back and Caoimh (Kelleher) and Wataru (Endo) from a specific moment on. So, the game is open, that means you can win it and obviously Macca had an idea after 98 minutes. A wonderful ball, (a) really wonderful piece of football and Darwin is there and scores the goal. A really cool afternoon for us in the end."
