Fernando Torres kept Liverpool's dream of a first English league title in 19 years alive with a stoppage-time winner at Portsmouth but Chelsea look dead and buried after yet another stumble.

Rafael Benitez's side twice came from a goal down at Fratton Park before Torres, left on the bench until 15 minutes from time, met Yossi Benayoun's cutback with a bullet header to seal a 3-2 win that lifted the Reds a point clear of Manchester United at the top of the table.
