Salah put the game beyond the Cherries after 48 minutes at Anfield.
Liverpool returned to the summit ahead of City's Sunday tie with Chelsea.
Jurgen Klopp hailed Mohamed Salah’s all-round performance in Liverpool's 3-0 win over Bournemouth.
The Merseyside club returned to the Premier League summit on Saturday thanks to goals from Sadio Mane, Georginio Wijnaldum and Salah.
The Egypt international’s 48th minute strike was his 20th league goal of the season and Klopp had nothing but praise for his impact in their triumph against the Cherries.
"The record is good but the performance was really good. He played an outstanding game," the Reds boss told a post-match news conference, after seeing his side bounce back from consecutive draws against Leicester City and West Ham.
"It was exactly the football he is able to play and that we want him to play; very involved in things, not only scoring but in the build-up as well, sometimes dropping deep, in the half-spaces, staying wide, all that stuff. That's exactly how he has to play and he did it in an outstanding manner.
"The goal he scored, I don't think you find a lot of players who would do what Bobby [Firmino] did in that moment. Most would try to shoot and be blocked, but he does a little pass and Mo is then obviously a pretty cool finisher."
Salah became the first Liverpool player to score 20 in consecutive seasons since Luis Suarez.
