Liverpool took over the top spot in the Premier League on Saturday thanks to a 4-0 win at Bournemouth, as champions Manchester City lost their unbeaten league record in a 2-0 defeat at Chelsea.
Mohamed Salah took his Premier League goal tally to 10 this season with his second Liverpool hat-trick, leaving his side one point ahead of City, who were undone by goals from N'Golo Kante and David Luiz at Stamford Bridge.
Liverpool manager Juergen Klopp said Liverpool were happy to be on top but were focused only on themselves.
"We are not really interested in other teams," he said. "We only have three days until Napoli [in the Champions League], which is a big one. It is Bournemouth celebrating day. Let's go home, have food and go again."
Tottenham are third after a 2-0 win at Leicester in the day's late match, with fourth-placed Chelsea still level on points with Arsenal, who edged out Huddersfield 1-0.
Salah was back to his best as Liverpool matched their 4-0 win at Bournemouth from last season in the lunchtime kickoff.
The first goal had a touch of fortune about it as Salah followed up Roberto Firmino's dipping shot to fire in the rebound, though TV replays suggested he was marginally offside.
There was no controversy about the second, though, as he shrugged off a foul to slip the ball into the corner, three minutes into the second half.
Steve Cook turned in Andy Robertson's cross to make it 3-0 on 68 minutes and Salah then added his third, twice rounding the goalkeeper before poking the ball home.
"Top of the table and [to] score three goals, fantastic win today and a clean sheet," Salah said.
"The last one was good, I was calm. I know everyone has high expectations for me but … the most important thing is being top of the table and to win each game."
Liverpool are now the only unbeaten team in the English league after City were beaten at Chelsea.
City dominated possession and had more shots but were beaten by Chelsea's first shot, through Kante on the stroke of half-time.
Beaten by Wolves last time out, Chelsea were a different team altogether and from their first corner, on 78 minutes, Luiz headed home the second goal.
"In general, we were fantastic," City manager Pep Guardiola said.
"I don't have any regrets. We came and showed we wanted to win. We created chances. They had one in 44 minutes and we conceded a goal. Sometimes that happens.
"It is emotional for me to see these players do what they do every three days. We were outstanding except for five to eight minutes."
Goals from Son Heung-min and Dele Alli gave Tottenham victory at Leicester, keeping them two points ahead of their fellow London sides.
Arsenal needed a stunning bicycle kick by Lucas Torreira after 83 minutes to seal the win against a valiant Huddersfield team.
"These goals help the team to keep winning, keep improving and keep building confidence," Torreira said.
"We have a fantastic team and a great group and we enjoy playing together."
Manchester United shrugged off a poor recent run as they beat bottom side Fulham 4-1, Ashley Young, Juan Mata, Romelu Lukaku and Marcus Rashford scoring the goals.
United manager Jose Mourinho said Fulham's improved performance in the second half denied his side a bigger margin of victory.
"I understand clearly there were reasons for the second half not being as good as the first, but still a good result, an important result," he said.
Burnley moved out of the bottom three after a 1-0 victory over Brighton.
Cardiff edged further from danger with their own 1-0 win over struggling Southampton in Ralph Hasenhuettl's first game in charge of the Saints while West Ham beat Crystal Palace 3-2.
