When you mention Champions League classics in recent history, Chelsea's 4-4 draw at Stamford Bridge against Liverpool ranks high up.
The Blues made it into the semifinals of the competition with a 7-5 win aggregate, but the match at the Bridge that night will forever remain edged on many fans' minds.
Chelsea carried a 3-1 win from the first leg at Anfield and needed any draw to qualify, even though a loss with a single goal margin could have still seen them through.
The Blues were however shocked as they found themselves trailing 2-0 at the break, thanks to goals from Fabio Aurelio and a Xabi Alonso penalty.
Petr Cech, in goal for the Blues, was caught off by Aurelio's free-kick from 30 yards out with just 19 minutes on the clock, and they doubled their lead after Branislav Ivanovic was adjudged to have handled the ball inside the box.
Alonso stepped up to bury it beyond Cech and into the top corner, momentarily giving his side a lead in the tie going into the break as the 3-1 lead from was wiped out.
Chelsea then turned the game on its head in the second half, scoring three goals to lead 3-2 on the night.
First, a mistake by Pepe Reinga allowed a rather harmless touch by Didier Drogba on a Nicholas Anelka cross to creep into the net in the 51st minute before a thunderous freekick from Alex six minutes later drew them level on the night.
It was 3-2 on the 76th minute as Drogba, who was having a wonderful night found Frank Lampard, and his shot once again crept under Reina.
But the lead lasted just five minutes as Lucas Leiva equalized to level scores 3-3 on the night with a deflected shot off Michael Essien and give the Reds some hope.
They then scored again two minutes later through Dirk Kuyt to lead 4-3 on the night and set tense final minutes as they needed to only score once to advance.
Lampard, however, settled the tie with his second of the night and fourth for Chelsea, scoring with a minute of regulation time remaining to crush their hopes.
The Reds, under Rafael Benitez at the time, missed Steven Gerrard's services as he recovered from an injury, and maybe it could have been different if he played.
The Blues advanced to face Barcelona in the semis.
