The Polish striker lined up at the Allianz Arena in a Barcelona shirt after completing a £45 million move to the Spanish side over the summer.
Lewandowski was supposed to be the man to finally lead his side to glory over Bayern after their recent struggles in the fixture, but it wasn’t to be for the master marksman.
The 34-year-old had to watch as his former team – who he scored 344 times for – secured a 2-0 victory on home soil thanks to second half goals from Lucas Hernandez and Leroy Sane.
For Lewandowski, it was a rare night to forget in the final third.
In the first half of proceedings, Poland’s record scorer missed two huge chances that he would normally put away with ease.
The first saw him send a volley over the bar from close-range, while the second was a far post header that was straight at Manuel Neuer.
Overall, Lewandowski had seven shots on goal, but failed to score with any of them.

Video: Lewandowski’s performance on return to Bayern
Yeah, that’s not the ruthlessly clinical Lewandowski we all know and love. The less said about his free-kick attempt in the second half, the better, although Pedri did rob of him of a brilliant assist shortly before.
It looks as if the pressure of returning to Bayern with a different team got to him a tad, as he was snatching at chances – something we rarely ever see from him on the pitch.
But despite the fact Lewandowski struggled in front of goal at the Allianz and was pocketed to a degree by the brilliant Dayot Upamecano, he was still one of Barcelona’s highest-rated players from the match over on SofaScore.
Lewandowski received a 7.0 rating for his efforts, which was only bettered by Marcos Alonso (7.2), Sergio Busquets (7.2) and teenage sensation Gavi (7.1).
So it certainly wasn’t a bona fide ‘disasterclass’ from Barcelona’s new talisman in Bavaria, but it also wasn’t a performance the man himself will be proud of or eager to revisit in the future.
Lewandowski has enjoyed a stellar start to life with the Blaugrana overall, though. He’s currently the top scorer in La Liga with six goals to his name from just five appearances.
The striker will be eager to add to his tally on the weekend before players jet off around the world for the international break, with Barcelona set to host Elche at Camp Nou on Saturday afternoon.
