Title holders Paris Saint-Germain squandered a three-goal lead at Parc des Princes but survived to take a one-goal advantage into the second leg in Munich.
Paris survives Bayern's comeback
Paris Saint-Germain beat Bayern Munich 5-4 in the Champions League semifinal first leg in Paris on 28 April, leaving the defending champions with a slender advantage ahead of the return fixture.
PSG built a commanding three-goal lead before Bayern fought back to level the tie, only for the hosts to find a decisive fifth goal and claim the win, the club said in post-match statements.
The nine-goal contest has since been hailed by players and supporters as one of the finest football matches across any competition this season.
A record-breaking night
The result is described as record-breaking for the Champions League semifinal stage, with the combined nine goals representing an unusually high-scoring encounter at that round of the competition.
PSG travel to Munich for the second leg defending that 5-4 aggregate lead. Both coaches have pledged more attacking football when the sides meet again, setting up the prospect of another open contest at Allianz Arena.
The wider semifinal picture
Elsewhere in the last four, Arsenal drew 1-1 at Atletico Madrid in the other semifinal first leg. Arsenal scored one penalty but were controversially denied a second by a VAR intervention, leaving the tie level ahead of the return in London.
