Liverpool striker Fernando Torres returned to form with a match-winning brace against table-topping Chelsea.
The Spanish hitman has struggled for form at the start of the season, but appeared rejuvenated in what was a vital clash for the Reds at Anfield.
Torres opened the scoring on 11 minutes, latching onto a perfect pass from Dirk Kuyt and lifting the ball over Petr Cech whilst under pressure from John Terry.
The finish was Torres of old, and lifted the Merseyside outfit to a fine first-half display that was capped off by the striker's second goal.
Raul Merieles found his teammate in space on the edge of the box, and 'El Nino' curled in a beautiful finish to deliver a hammer-blow to the current Premier League champions on 44 minutes.
Didier Drogba was introduced at half-time to try and spark the Stamford Bridge outfit into life, but after Ramires headed over Jose Reina was equal to the task with some smart saves from Yuri Zhirkov and Florent Malouda.
Liverpool, who set out their defensive stall in the second-half, could have wrapped it up but Cech saved with his legs from a Kuyt half-chance.
Reina again denied the Blues late when the Spanish stopper tipped Nicolas Anelka's drive onto the bar, with Jamie Carragher denying Drogba when the Ivorian looked certain to score from the rebound.
Liverpool were denied a penalty in injury-time when Maxi Rodriguez appeared to be pulled down by Cech, but it was immaterial to the result as Roy Hodgson's side gained a well-deserved three points.
Whilst Torres stole the headlines with his stunning first-half performance, Lucas Leiva produced one of his finest displays in a Liverpool shirt to help the Reds win a crucial midfield battle against Carlo Ancelotti's out-of-sorts opponents.
