The stage is set for an eagerly anticipated clash between Chelsea and Bayern Munich in the Champions League knockout phase.
The two sides have met five times this century with the most recent being the UEFA Super Cup final in 2013.
The most famous, however, is the historic final at the famous Allianz Arena on May 19, 2012.
The Blues, against all odds, lifted the title despite meeting continental heavyweights en route to the finals.
Road to finals
Chelsea maneuvered through tricky fixtures right from the Round-of-16, starting with a knockout match against Napoli where they trailed 3-1 after the first leg.
The then manager Andres Villas-Boas was shown the door with Roberto Dimatteo taking over on an interim basis and led them in the second leg at Stamford Bridge.
The Blues then showed real intent at the Bridge a fortnight later. They battled and overturned the 3-1 first-leg loss with goals from Drogba, Terry, and Lampard before a Branislav Ivanović goal in extra time decided the tie, winning 5-4 on aggregate.
Up next, Benfica in the quarterfinals
The Blues picked a 1-0 win away but the Portuguese side caused them all sorts of trouble in the return leg.
Frank Lampard scored the opener for the Blues in the first half to give his side a comfortable 2-0 lead on aggregate, but the visitors scored on the 85th minute to rock Stamford Bridge, setting a tense finale to the match.
Raul Meireles, however, scored on the 95th minute with a thumping shot to help his side book a ticket in the semis where the mighty Barcelona hid in waiting.
Barcelona in Semis
This is perhaps one of the most epic matches in the Champions League in recent years. Didier Drogba scored the lone goal in the first leg at Stamford Bridge, and everyone expected a bloodbath in the second leg at Camp Nou, after all, they were the mighty Catalans at their pinnacle.
Everything seemed to be going well for Chelsea until Sergio Busquets scored the opener on the 35th minute, and it got worse as John Terry was red-carded two minutes later, leaving his side to battle the second half with 10 men.
Chelsea seemed dead and buried when Iniesta scored a second on the 43rd minute, but Lampard and Ramires combined well to score on the stroke of half-time, the Brazilian chipping over Victor Valdes with the deftest of touches.
Lionel Messi had the chance to make it 3-1 but he hit the crossbar and this came back to haunt them.
Chelsea held on and for a moment, it seemed the match will end 2-1 in favor of the home side until Fernando raced half the length of the pitch deep in added time to score the famous goal that assured the Blues of a place in the finals.
Chelsea had four of their first-team players suspended; John Terry, Branislav Ivanovic, Ramires, and Raul Meireles were all out.
The London side suffered for long spells at the Allianz Arena, defending with their lives and trying to hit the Bavarians on the counter.
The lack of key players meant they played with an understrength team which included a certain Ryan Bertrand, 23, who was making his debut in the match.
The hosts were patient, toying around with the Blues, and it paid off when Thomas Muller headed in at the far post on the 83rd minute to give them the lead, and it seemed like the only goal needed to decide the match.
Then stepped forward the 'man of the finals'; Didier Drogba with two minutes to go.
Substitute Fernando Torres, who had replaced Salomon Kalou, won a corner which was neatly floated in and the Ivorian rose highest, partially thanks to Jerome Boateng's push that gave him the power to turn and expertly head past Manuel Neuer to send the Blue fans into a frenzy.
The match went to extra time and Drogba almost turned villain when he gave Bayern a penalty on the 95th minute.
Petr Cech, however, saved the resulting Arjen Robben kick and at that moment, everyone knew it was written in the skies, luck was on Chelsea's side.
The match ended 1-1 in regulation and extra time forcing the clash to head to penalties.
Juan Mata's first penalty was saved as Lahm, Gomez and Neuer scored their three first kicks. David Luiz and Lampard scored for the Blues before Cech made a crucial save to deny Olic and pull his side level.
Ashley Cole then buried Chelsea's third, before Schweinsteiger hit the post to swing the advantage back to Chelsea.
Didier Drogba scored the final and winning penalty as the Blues rose to the top of European football on a memorable night.
Bayern totally dominated, registering 35 shots, winning 20 corners across the whole 120 minutes, compared to Chelsea's nine efforts and just one corner - from which Drogba headed home the equalizer.
