Ahead of their UEFA Champions League quarter-final clash, we take a look at players that have represented both Barcelona and Borussia Dortmund.
Two clubs rich in footballing history, meetings between the two have been sparse.
They first met in 2019 where a forgettable 0-0 draw unfolded in front of spectators at the Nou Camp. The reverse fixture, however, was much more like it with Lionel Messi, Luis Suarez and Antoine Griezmann all getting on the scoresheet in a 3-1 Barcelona win.
Seven players in total have donned the shirt of both clubs, most recently, Polish forward Robert Lewandowski who kicks off our list.
Back in 2010, Blackburn Rovers was the intended destination for the striker were it not for a volcanic ash cloud. With the move off, Borussia Dortmund were the beneficiaries, and what a signing it turned out to be.
The Pole fired BVB to a league and cup double, scoring 103 goals in 187 appearances before signing a pre-contract agreement with Bayern Munich in 2014.
His fine form continued in Bavaria and as the summer of 2022 rolled around, Lewandowski had only Gerd Muller ahead of him in Bayern's all-time leading scorers list.
When Barcelona paid a fee of £38m for the then 33-year-old, they made him the most expensive Polish footballer of all-time as well as Bayern Munich's most expensive sale.
The goals haven't stopped in Spain; Lewandowski won the Pichichi in his first season and then became just the third-ever player to reach a century of strikes in the UEFA Champions League.
Having hit 21 goals in his final season at Saint-Etienne, expectations were high when Borussia Dortmund paid £11m for the Gabonese forward.
Years of success followed and after being named 2015/16 Bundesliga Player of the Year, he hit 31 goals in 32 games to finish as the league's top goalscorer just one season later.
2017/18 was to be his last in Germany, however, as Arsenal's £53m January bid was too good for BVB to turn down and he left as the club's eighth-highest scorer.
By the time he joined Barcelona in 2022, he had lost some of the pace that gave him notoriety earlier in his career. Despite this, a goal return of 13 in just 24 matches showed that he still retained his striking instincts.
Crucial to Borussia Dortmund's maiden domestic double-winning side, Ilkay Gundogan is still loved by the BVB faithful.
The adaptation to a challenging Jurgen Klopp style wasn't seamless but Gundogan soon became central to everything Dortmund did.
His equaliser from the spot against Bayern Munich in the 2013 UEFA Champions League was actually his first in regular-time for the club. Despite going on to lose the match, the midfielder received praise for his performance.
2016 saw Gundogan make his move to England and after lifting 14 trophies with Manchester City, he joined Barcelona.
The German struggled to make the same impact in Spain, but a goal against Real Madrid meant he became the club's second-oldest El Clasico scorer.
A graduate of the famous La Masia academy, Marc Bartra won everything there is to win for his boyhood club.
Making 103 appearances in six years with the first-team, Bartra was admittedly a squad player but he did chip in with a goal as Barcelona lifted a continental treble during the 2014/15 season.
His move to Germany was up next and the Spaniard continued his trophy-winning habit, lifting the DFB-Pokal in his first season at the club.
Blessed with frightening pace and a natural two-footedness, Ousmane Dembele flourished in his sole season with Borussia Dortmund.
Scoring 10 goals and assisting a further 21, Barcelona quickly came calling.
A £112m transfer fee made the Frenchman the joint-second most expensive player of all-time.
Sadly, injuries plagued Dembele's stint in Barcelona as the winger missed over 140 games with various problems.
A product of Valencia's academy, Paco Alcacer demonstrated his eye for goal very early into his career.
After scoring 43 goals for Los Che, he was rewarded with a move to Barcelona with Munir heading in the opposite direction as part of a swap deal.
Breaking into a forward line containing Lionel Messi, Luis Suarez and Neymar was always going to be difficult and he was subsequently loaned out to Borussia Dortmund.
It was here that Alcacer enjoyed the most prolific spell of his career, scoring 26 times in 46 games, a run of form that would earn him a permanent move to the club.
The seventh and final player on the list, Boateng was never actually a permanent signing for either club.
He joined BVB on loan from Tottenham in 2009, where Dortmund were reportedly keen on signing the Ghanaian but were prevented by financial constraints.
A decade would pass before he found himself at Barcelona. After his career appeared to be nearing a conclusion, he described his shock loan move as a "dream come true".
Ultimately, Boateng appeared just four times for the club before making a move to Fiorentina the following season.
