Curtis Jones struck his first Premier League goal as Liverpool secured their 24th successive home league victory with a 2-0 win against Aston Villa.
Liverpool were frustrated for long spells by a resolute Villa side with Mohamed Salah's 37th-minute shot, saved by former Red Pepe Reina, their best chance of the first half.
After the break, Anwar El Ghazi's angled drive was kept out by Alisson.
Sadio Mane broke the deadlock on 71 minutes, firing home in the area from Naby Keita's incisive pass.
Substitute Jones then celebrated signing a new deal earlier in the week by adding a second in the 89th minute.
Liverpool extend their lead to 23 points over Manchester City.
Aston Villa remain 18th on 27 points, one point from safety.
