PSG reaches Champions League semi-finals after beating Bayern on away goals
set up David Alaba for a first-time shot that Keylor Navas saved. The ball looped up to Choupo-Moting and he headed in.
The Cameroon forward, who scored once in 10 Champions League appearances across two seasons at PSG, now had his second goal against his old club in this tie while standing in for Lewandowski.
Bayern could even have scored again before the break as a thunderous strike by Alaba was turned behind by Navas, keeping PSG ahead overall on away goals.
A goal for the home side would have calmed the nerves as they looked to avoid another dramatic exit from the Champions League like so many before over the last decade.
