The Blues have a storied history with several of the clubs we have been pitted against in the league phase of this season's UEFA Champions League. And here we reflect upon six memorable matches from our previous meetings...
The draw for the league phase took place in Monaco this evening and the Blues will host Barcelona, Benfica, Ajax, and Pafos at Stamford Bridge. We will also travel across the continent, with trips to Bayern Munich, Atalanta, Napoli and Qarabag.
History will be made against Pafos and Atalanta; we have not faced either club before. Yet for our other six opponents, the league phase will present an opportunity to renew rivalries – and conjure more than a few memories of our 2012 triumph.
But let's begin back in 2005, with the Blues facing a side we have faced on 14 occasions in the Champions League...
Chelsea 4-2 Barcelona | Champions League Round of 16 second leg | 8 March 2005
This remains one of the greatest matches in Chelsea history, and further fuelled the rivalry between the Blues and the club from Catalonia.
Trailing 2-1 from the first leg of the tie, the Blues needed to produce something special against a Barcelona side that included the likes of Carles Puyol, Xavi, Andres Iniesta, Samuel Eto'o and Ronaldinho.
The Blues were outstanding from the off in front of a raucous Stamford Bridge crowd. We raced into a 3-0 lead on the night with Eidur Gudjohnsen, Frank Lampard and Damien Duff all scoring inside 19 minutes.
Ronaldinho netted a penalty in response and then netted arguably the best goal we have conceded in Europe: an audacious toe-poke that arched beyond Cech and left mouths agape and some home fans applauding.
With that goal, Barcelona were heading through on away goals. Step forward, John Terry. With a quarter of an hour remaining, the Blues captain got his head to a corner and, with an assist from Ricardo Carvalho, who was blocking Victor Valdes, found the net to send us through.
Chelsea 4-1 Napoli aet | Champions League Round of 16 second leg | 14 March 2012
Having suffered a 3-1 defeat in Naples during the first tie of this tie, it looked a tall order for the Blues to progress.
A change had been made in the dugout with Roberto Di Matteo installed as interim head coach after the departure of Andre Villas-Boas, and the Blues legend oversaw a famous victory that put us truly on the path to European glory.
Goals on either side of half-time from Didier Drogba and Terry drew us level in the tie, and would've been enough for the Blues to progress on away goals. But when Gokhan Inler rifled home a shot from the edge of the box, we had to go again.
A Lampard penalty with 15 minutes to play forced extra time, in which Branislav Ivanovic swept home a Drogba cross to the delight of everyone inside Stamford Bridge. The drama of that Champions League run was far from done, however.
Chelsea 2-1 Benfica | Champions League quarter-final second leg | 4 April 2012
We remain in the spring of 2012, where a goal from Salomon Kalou, after good work from Fernando Torres, had given us a slender advantage heading into the second leg at Stamford Bridge.
And when Frank Lampard converted a 21st-minute penalty in front of the Matthew Harding, our place in the last four looked secure.
However, when Javi García netted with five minutes to play, a nervy finish ensued. One more goal for the Portuguese side and they would progress on away goals.
Thankfully, we gave ourselves breathing room in stoppage time. And in style! After John Mikel Obi cleared a late Benfica free-kick, Raul Meireles collected possession, advanced down the pitch, and then rifled a shot into the net to restart jubilant celebrations inside Stamford Bridge.
Chelsea 1-1 Bayern Munich (aet, 4-3 pens) | Champions League final | 19 May 2012
It was at the home of the German giants that Chelsea were crowned European champions for the first time – and it's why Munich will always hold a special place in the hearts of Blues supporters.
From Drogba's physics-defying late header to level the contest, to Petr Cech's penalty heroics in extra time and the penalty shootout, several Chelsea players further cemented their places in the club's history that May evening in Bavaria.
And now the latest crop of talented Blues will have the opportunity to enhance their legacies at the Allianz Stadium.
Qarabag 0-4 Chelsea | Champions League group stage | 22 November 2017
A game not quite as famous as others on this list, but one that will be fondly remembered by the supporters who made the 6,000-mile round trip to Azerbaijan.
Eden Hazard opened the scoring from the penalty spot after Willian was fouled by Rashad Sadygov, who was shown a red card.
Our brilliant Belgian turned creator, producing a lovely back-heeled pass for Willian to net our second ten minutes before the half-time interval.
Cesc Fabregas converted our second penalty of the evening, also won by Willian, with 17 minutes left to play. And the Brazilian winger then rounded off an impressive night's work by firing home from the edge of the box.
The victory secured our place in the knockout stage and ensured those who had made the trip went home happy.
Chelsea 4-4 Ajax | Champions League group stage | 6 November 2019
This game did not end in victory for the Blues, but was the scene of bedlam inside the Bridge late in the second half.
We had fallen behind inside two minutes after a Tammy Abraham own goal, but were quickly level when Jorginho converted a penalty. Two swipes of future Blue Hakim Ziyech's left foot soon changed things, as he crossed for Quincy Promes to head home and then netted directly from an Ajax corner.
And when Donny van de Beek struck Ajax's fourth ten minutes into the second half, it looked a tall order for the Blues to rescue anything from the game.
However, Cesar Azpilicueta reduced the deficit when he stabbed home a corner and, with just over 20 minutes to play, Ajax defenders Daley Blind and Joel Veltman were both shown red cards and a spot-kick was awarded to the Blues.
Jorginho netted once again, and momentum was entirely with the Blues. Cue Reece James. From a corner, Kurt Zouma crashed a header off the bar and the rebound fell to our current skipper to rifle a shot beyond Andre Onana.
Stamford Bridge erupted and although we weren't able to find the winner and truly complete the comeback, it's a game that has lived long in the memory of supporters.
