It gave 3-3 overall and the team's 3-2 win away laid the foundation.
It was highly dramatic right into the four-minute extra time in Paris before the home players could bounce against each other and celebrate the victory.
In the end, Neymar was able to burst into a big smile.
Within five minutes of the end of the first half, it was the Neymar show.
He dotted the post twice and the crossbar one.
At the final post meeting, Bayern scored 1-0.
The ball went after goalkeeper return to ex-PSG player Eric Maxim Choupo-Moting who vigorously nodded it and PSG defender Presnel Kimpembe in goal.
No matter how unfair and the tension increased at the Parc des Princes.
Then it was 3-3 overall and Bayern was a goal from moving on.
A quarter from the end, Kylian Mbappé thought he had given Paris SG 1-1, which had then forced Bayern to score two goals to move on, but an offside near midfield made the goal fail.
He ran almost half a plane half and pounded the ball into the net roof - to no avail.
