Bayern Munich fought back to claim a 2-1 win at FC Copenhagen.
Bayern dominated possession but it was Copenhagen who took the lead when Lukas Lerager fired in after the visitors failed to clear.
Bayern needed some individual brilliance from Jamal Musiala to level as he shook off several challenges on the edge of the box and found the bottom corner.
Two Bayern substitutes combined for the winner, with Thomas Muller holding off a challenge and then teeing up Mathys Tel to score.
