The two sides would meet at the last-16 stage of Europe's elite club competition and Barcelona would go into this one with a controversial 2-1 lead from the first-leg.
Following the first-leg, Chelsea manager Jose Mourinho claimed that he saw his Barca counterpart Frank Rijkaard enter referee Anders Frisk's dressing room at half-time of the first encounter.
Didier Drogba would also be shown a debatable red card for a second-half challenge on goalkeeper Victor Valdes and would miss the second-leg tie at Stamford Bridge.
Despite being a goal-behind from the first-leg, Chelsea would score three goals in eleven minutes to give themselves a 3-0 lead on the night after just 19 minutes played.
The first saw Mateja Kezman's pass from the right find Eidur Gudjohnsen, who turned defender Juliano Belletti and slammed home from inside the area.
Nine minutes later, Chelsea would make it two. Joe Cole's brilliant run from the right saw him unleash a shot that was well saved by goalkeeper Victor Valdes, but Frank Lampard was in the right place with the follow up to put the score at 2-0.
Cole would be involved again minutes later. His through-ball was latched onto by Damien Duff and he made no mistake in scoring low past the goalkeeper.
Stamford Bridge joy lasted all of six minutes as Barcelona put themselves back in contention on 27 minutes. Italian referee Pierluigi Collina ruled that defender Paulo Ferreira had handled the ball inside the area and Ronaldinho scored the resulting penalty.
The Brazilian then produced a moment of magic to level the aggregate score just after the half-hour mark. Gaining control outside the area, and with Chelsea defenders in front of him, the midfielder leaned back and struck the ball past a dazzled Petr Cech in the Chelsea goal.
Chelsea were handed a massive let-off with just under 20 minutes remaining. Andres Iniesta would weave his way into the box before Cech tipped his shot onto the post. The net waiting in front of him, Samuel Eto'o would uncharacteristically hit the ball over the bar.
Captain John Terry would be the hero for his side. He powered Duff's corner past Valdes, who claimed he had been fouled by Ricardo Carvalho in the build-up to the goal.
