The striker, who arrived for title rivals Borussia Dortmund in 2014, has penned fresh terms and recommitted himself to the club until 2021
Bayern Munich have announced that Robert Lewandowski has extended his contract until 2021.
The 28-year-old, who joined from Borussia Dortmund in 2014, has been in talks with the club in recent weeks over the renewal of a deal that was due to expire in 2019.
Bayern president Uli Hoeness stated last week he was "pretty sure" that Lewandowski would commit his future to the club, despite speculation linking him with a move to Real Madrid.
