Liverpool boss Jurgen Klopp was delighted after their 3-0 win at Champions League opponents Ajax.
The win sees Liverpool reach the round of 16.
Klopp later said: "They had a top half an hour from a specific moment where they created a lot of pressure and did really well and we had to defend with a lot of passion.
"We scored a goal which was exceptional. The second half we had a really good start and controlled the game from then on.
"We changed system again a little bit, we had to. We thought it would make sense. Ajax are a good football team and full of confidence always and you have to adjust. We did that and fine.
"It is clear. We are through to the knockouts and I will never take that for granted. Really helpful for the club, of course it gives the lift. Tonight we all feel great and we have a few days to prepare for Leeds."
On goalscorer Nunez, he added: "I think even he was surprised! [when Firmino passed for the shot on the woodwork]. He had a really good game in both directions, helped defending and played with a big heart today so hopefully we took him off early enough!"
