Bayern Munich secured top spot of Champions League Group B after demolishing Red Star 6-0 away on Tuesday.
Lewandowski was the best player on the pitch, and the best player in the competition on the night as he scored four of those goals, each from relatively close range to highlight his danger inside the box.
The spurt of goals came within a period of just 14 minutes, making it the quickest time a player has taken to score four in the history of the Champions League.
The first was a simple penalty, while he took advantage of a Corentin Tolisso downward header inside the box to prod home his second.
The hat-trick goal was classic Lewandowski as he darted ahead of the goalkeeper to divert a cross home. He earned the fastest four-goal haul record by latching on to a pass - which wasn't initially meant for him - in behind the Red Star defence before finishing in typical, clinical fashion.
