The Reds beat Watford 2-0 at Anfield to move 10 points clear of Leicester City, who were held to a 1-1 draw at home by struggling Norwich City.
There was also frustration for a top-four side at Stamford Bridge, where Chelsea failed to score for the second time in three Premier League home games as they succumbed 1-0 to Bournemouth.
Manchester City suffered no such slip-up when they travelled to Arsenal on Sunday, as a 3-0 win for the third-placed defending champions moved them to 14 points behind Liverpool.
Tottenham nudged up to fifth after beating Wolves 2-1 to offer further evidence that Jose Mourinho has addressed some of the problems his side faced on the road under Mauricio Pochettino.

Take a deep dive into the big stories of the weekend in our Premier League Data Diary.
REDS STREAK RANKS THIRD AFTER TRICKY HORNETS TEST
Goals from Mohamed Salah and some wayward Watford finishing ensured Liverpool claimed a 2-0 win at Anfield to extend their unbeaten Premier League run to 34 games.
Only Arsenal (49 between May 2003 and October 2004) and Chelsea (40 between October 2004 and October 2005) can boast longer undefeated sequences in the competition, and the Reds have won their last 16 league games at Anfield.
Five more consecutive home wins would see Jurgen Klopp's men match the record (21) set by Bill Shankly's title-winning Liverpool side between January and December 1972.
Salah's double takes his goal tally to 84 in 126 appearances for Liverpool, eclipsing Luis Suarez's record of 82 goals in 133 games for the Reds.
Watford have taken just nine points from 17 league games this season, and the omens for them are not good: all of the nine teams to accumulate nine points or fewer after 17 Premier League matches have been eventually relegated.
HONEYMOON PERIOD A DISTANT MEMORY FOR LAMPARD
After seeing Chelsea lose just two of his first 12 Premier League games in charge, Frank Lampard watched his charges slip to a fourth defeat in five against Bournemouth on Saturday.
The 1-0 reverse at Stamford Bridge came courtesy of Dan Gosling's first league goal since April and left the Blues with just one fewer home defeat (five) in all competitions this season than they suffered in 62 games over 2017-18 and 2018-19 combined.
Chelsea have lost two of their last three top-flight home games, as many as they had in their previous 28 at Stamford Bridge, and failed to score in both of those defeats.
Since their promotion in 2015, no side has won more Premier League away game at Chelsea than Bournemouth (three, level with Liverpool).
MOURINHO'S MEN MAKE PROGRESS ON THE ROAD
Prior to Jose Mourinho's arrival as Tottenham boss, Spurs had failed to win a Premier League away game this season. But since he took charge they have won two out of three in the league on the road.
Lucas Moura's spectacular solo goal gave them the lead at Molineux and the Brazilian has now scored three goals in five top-flight appearances under Mourinho.
Wolves pulled level after 67 minutes of a scintillating game, Adama Traore scoring his fourth goal in 26 appearances in all competitions this season - twice as many goals as he scored in his previous 82 matches.
But Jan Vertonghen restored Tottenham's lead in second-half stoppage-time, inflicting a third home league defeat for Wolves in 2019 while extending Mourinho's record of not losing Premier League games when his side score first to 54 games since October 2015.
CHAMPIONS CRUISE AGAINST SHOT-SHY GUNNERS
Arsenal shipped three goals in 40 first-half minutes as they lost 3-0 at home to Manchester City, which left the Gunners with one win from their last nine Premier League matches.
Freddie Ljungberg's men are without a win at home in six games across all competitions - the club's longest such run since an eight-game streak between December 1994 and February 1995.
Kevin De Bruyne produced a masterclass at the Emirates, scoring either side of Raheem Sterling's tap-in, which he set up, to take his goal involvement tally to 19 in the league this season (seven goals and 12 assists).
Sterling's effort was his seventh away goal in the league this season - his joint-highest return on the road in a single campaign (also seven in 2017-18).
While City were prolific, Arsenal mustered just one shot on target all game - their joint-fewest in a Premier League game at Emirates Stadium (one v Everton in 2010, and v Chelsea in 2015 and 2016).
