On 22 September 2015, Lewandowski set a Bundesliga record by coming on as a substitute with Bayern trailing 0-1 to Wolfsburg and scoring five goals in 8 minutes and 59 seconds, the fastest by any player in Bundesliga history, to take a 5-1 lead.
Four days later, he scored twice in a 3-0 win at 1. FSV Mainz 05, the first goal being his 100th Bundesliga goal on his 168th appearance, a league record for a foreign player.
