Liverpool's first game back at Anfield after becoming Premier League champions was a quiet affair as they saw off the challenge of Aston Villa 2-0.
Liverpool have failed to find their form since winning the title and the first half passed without either side putting together any dangerous chances.
The result means Aston Villa remain rooted in the relegation zone while Liverpool go 23 points clear of Manchester City.
The Reds dominated possession in the first half, securing 72% of the ball, but managed just one attempt on target. Aston Villa were largely happy to let Liverpool pass the ball around before launching into a counterattack.
The pace improved in the second half but Aston Villa came out the brighter of the two sides.
After running off an injury sustained in the first half, Jack Grealish was pivotal to several big chances for Aston Villa.
On 51 minutes the England international had a powerful shot parred away by Allison and he led another attack moments later that saw Anwar El Ghazi's low shot causing the Liverpool defence trouble.
The triple substitution proved to be the fire Liverpool needed and it took just over 10 minutes for Mane to score the game's first goal.
Keita struck a low ball across the box and Mane hammered it in from 10 yards.
Firmino nearly made it 2-0 on 76 minutes but former Liverpool keeper Pepe Reina was ready for the curling shot and pushed it wide.
Substitute Jones made it 2-0 on 89 minutes with a left-footed shot following a cross into the box from Robertson which was headed into Jones' path by Mohamed Salah.
Klopp said after the game that it was a "very difficult match" for a variety of reasons.
"Villa are obviously organised and made it tricky for us. The wind made it tricky for both but it was really hard to play normal football," he said.
"We had to stay on track and do the right things and in the second half we had more of the good moments. You could see we needed time to get used to it. Two situations could have been penalties, we were unlucky but I'm fine -- we are where we are because we win difficult games."
Liverpool are on course to beat Manchester City's mark of 100 points in a Premier League campaign but the champions are not focused on breaking records, Klopp insisted.
"We didn't come here and have the numbers we have because we thought about breaking records. We were always focused 100% on the game and that will not change," said Klopp, whose side made it 17 wins out of 17 games at Anfield this season.
"If we want to have record points pretty much we have to win all the games, it's not complicated. The boys know it and it's not necessary to mention it to this group."
Liverpool need 12 points from their final five games to beat City's tally from the 2017-18 season.
