Mane hit a stunning goal in the 2-1 win.
Reds boss Jurgen Klopp stated: "It's obvious Sadio is unbelievably important for us.
"In so many moments he is strong and quick. In the other moments it doesn't click and then he scores a goal like this and you think, 'wow!' When he came into the dressing room the whole team got up and gave him [a round of applause] because they know. He will be back on top. He makes steps, that's why I took him off. It's a situation where sometimes you get an injury, and we need him so much for all the things coming.
"That's it. I am happy. I had a lot of players in moments where it was not clicking, if you want, but they never scored. Sadio still scores, so that's really cool."
