Liverpool survived a late scare with 10 men to hold on for a 2-1 victory over Brighton, stretching their lead to 11 points at the top of the Premier League.
Virgil van Dijk scored both goals, and Juergen Klopp's side held on in a nervy finale after Alisson was sent off to claim their 14th straight league victory and extend their unbeaten run to a club-record 31 games.
Earlier in the day, reigning champions Manchester City were held to a 2-2 draw at Newcastle United.
Leicester City will cut Liverpool's lead to eight points if they beat Everton on Monday (NZ time).
Van Dijk headed hosts Liverpool in front from a Trent Alexander-Arnold corner on 22 minutes and the fullback then floated in a free-kick for the Dutchman to double their lead six minutes later.
Klopp's side were coasting, but Alisson gave Brighton a lifeline when he handled the ball outside of his area.
Quick thinking from Lewis Dunk saw him rifle in a free-kick as the Liverpool defence switched off.
Although substitute goalkeeper Adrian had to make a couple of saves in the closing minutes, Liverpool held on to extend their lead at the top.
"We should have gone better than we did in the second half, but you have to give them credit as well," Van Dijk said.
"We have to deal with it and manage the game a little bit better. We could have done that better today, but we won, and that's the most important thing."
City manager Pep Guardiola was left to rue missed chances as his side slipped up with a draw at Newcastle.
Raheem Sterling put City in front on 22 minutes before Jetro Willems equalized, but Kevin De Bruyne looked like he had won it when he smashed in a second off the underside of the bar eight minutes from time.
But Jonjo Shelvey swept in the equalizer six minutes later, and Newcastle held out for a vital point.
"The way we played was really good, we created good chances," Guardiola said.
"We only conceded two shots but unfortunately conceded two goals. We should have avoided the free-kick we conceded and Shelvey made the difference."
Elsewhere, Aaron Cresswell was the unlikely hero as West Ham won at Chelsea to climb to 13th, pulling well away from trouble and inflicting a second straight league defeat on Chelsea.
Dele Alli scored twice as Tottenham beat Bournemouth, though they were holding on at the end after two Harry Wilson goals for the visitors.
Wilfried Zaha scored his second goal in two games as Crystal Palace won 2-0 at Burnley to go 10th, while Southampton beat last-placed Watford 2-1.
