The prolific Pole brought up his half-century during a clash with Benfica on Tuesday.
That outing was his 77th in Europe’s elite club competition, with his bow made back in 2011.
He has been a regular source of end product since then, with Bayern continuing to benefit from the 30-year-old’s considerable talent.
Lewandowski is now the seventh man to record 50 efforts in the Champions League, with former Arsenal and Barcelona forward Henry briefly joined on that mark before hitting a second against Benfica.
The only players above him are Ruud van Nistelrooy, Karim Benzema, Raul, Lionel Messi and Ronaldo.
7 – Robert Lewandowski has become the 7th player to score 50 #ChampionsLeague goals, in his 77th game in the competition – only Ruud van Nistelrooy (62) and Lionel Messi (66) have reached the milestone in fewer appearances. Elite. — OptaJoe (@OptaJoe) November 27, 2018
Lewandowski’s efforts against Benfica were most welcome for Bayern, who have endured something of a domestic slump this season.
Niko Kovac finds himself falling under mounting pressure as a result, but his team are unbeaten in Champions League Group E.
Arjen Robben helped to preserve that record in midweek, with the former Netherlands international netting twice before Lewandowski got in on the act.
Only Van Nistelrooy (56) has more goals by a Dutchman in the Champions League than Robben’s haul of 31.
The hope will be that experienced figures continue to deliver the goods for Bayern, with it possible that continental action could provide the spark for a faltering Bundesliga campaign to be salvaged.
