Kingsley Coman repeated his 2020 Champions League final heroics as Bayern Munich beat Paris St-Germain in their last 16 first-leg tie.
The Frenchman volleyed home the winner early in the second half in Paris.
Lionel Messi started and Kylian Mbappe came off the bench after recent injuries, but neither could inspire a below-par PSG.
Mbappe looked to have rescued a late draw, however his goal was ruled out for offside in the build-up.
The Ligue 1 champions have now lost their last three matches in all competitions.
