Guus Hiddink's team led 3-1 after the first leg at Anfield but Fabio Aurelio's free-kick after an awful misjudgement from Petr Cech and Xabi Alonso's penalty put Liverpool in control at the break.

Jose Reina fumbled Didier Drogba's deft touch into his own net and Alex's thunderbolt free-kick levelled the scores on the night with two goals in six dramatic second-half minutes.

The inspirational Frank Lampard put the Blues 3-2 ahead, slotting home Drogba's intelligent cross.

The tie looked finished but Liverpool were not done yet and Lucas Leiva's deflected strike was quickly followed by Dirk Kuyt's near-post header.

It was 4-3 to Liverpool with seven minutes of normal time remaining and Stamford Bridge was stunned, while the Reds required just one more goal to complete a sensational victory on away goals.

But Lampard converted Nicolas Anelka's pass to level at 4-4 in the final dramatic action of a truly memorable game of football.
