Liverpool's Sadio Mane sealed a 1-0 win against West Ham United that moved the Premier League title chasers within three points of leaders Manchester City Saturday.
With City not in action until the derby against Manchester United Sunday, Liverpool took the chance to increase the pressure on the champions.
Mane netted in the 27th minute at Anfield with a close-range finish from Trent Alexander-Arnold's cross.
The Senegal forward's goal survived a Video Assistant Referee check for offside and that was all Liverpool needed to make it seven successive league wins.
Even if City beat United, Liverpool have a game in hand to keep the leaders within touching distance as they chase an unprecedented quadruple.
Defeat was a blow to fifth-placed West Ham's hopes of finishing in the top four, leaving them two points behind fourth-placed United.
All Premier League captains were wearing armbands in Ukraine colors this weekend and clubs held a minute's applause in a show of solidarity with the country following Russia's invasion.
