Liverpool recovered from a poor start to beat Swansea City 2-1 and move second in the Premier League football standings while Chelsea got back to winning ways at Hull City.
Outplayed for half the match by struggling Swansea and trailing to an early goal by Leroy Fer, Liverpool were a different proposition after the break and took the points thanks to a late James Milner penalty.
Liverpool, for whom Roberto Firmino equalised nine minutes after half-time, have won five of their opening seven matches and are on 16 points, two behind leaders Manchester City who play third-placed Tottenham Hotspur (14) Monday (NZ time).
"We could have done so much better in the first half," Liverpool manager Juergen Klopp told reporters. "It's not allowed that we accept a bad day.
"Even on a bad day you have to fight against the start in this game, you have to strike back in the game."
Chelsea, who had suffered back-to-back defeats by Liverpool and Arsenal, were held by Hull for an hour before curling shots from Willian and Diego Costa secured a 2-0 win that moved Antonio Conte's side into sixth spot with 13 points.
