The homework clearly paid off as Liverpool claimed a valuable 2-0 away win in the first leg.
Salah, who scored in the match, told reporters, via KingFut: "I think we did enjoy ourselves. We had a good game against a tough opponent and hopefully, we will do the same in the next game.
"I say it's always good when you score and the team win. That's the most important thing.
"We studied them [Leipzig] well the last couple of days and we know how they play, but we need to keep going and just carry on because the next game is going to be tough also against them.
"Hopefully we are going to play home; we never know because the rules, but hopefully we play at home and we qualify from there.
"I think the last game [Leicester City] we played also well until maybe the 75th minute, but it's football, you have to play 90 minutes good.
"I am not here to complain, but I am just saying hopefully that gives us more confidence and we keep winning."
