Liverpool manager Jurgen Klopp played down talk of a title challenge despite his side topping the Premier League for the first time since May 2014.
Two and a half years after the Reds finished two points behind champions Manchester City, a 6-1 win over Watford moved them one point clear of Chelsea.
City and Arsenal – third and fourth respectively – are one further back.
“We’ve started collecting points but we need to go on with this. Then we will see where we can end,” Klopp said.
