Born in Paris and raised at PSG, Coman scored the only goal when Bayern beat the French side in the 2020 Champions League final and he was again the sole scorer as the German champions put one foot into the quarter-finals.
PSG, who have now lost five games in all competitions in 2023, held firm in the opening half but were eventually subdued and failed to fight back despite finishing the game with Kylian Mbappe, Neymar and Lionel Messi all on the pitch.
Christophe Galtier’s side now face the prospect of a second elimination in a row in the last 16 on March 8 in Munich, although Mbappe’s high-octane display as a second-half substitute will have given them hope.
The stadium came to the boil when Mbappe replaced Carlos Soler, raising hopes that the France forward would bail out PSG on his comeback from a two-week injury layoff.
Before that, Eric Choupo-Moting had came close to doubling the tally for Bayern on two occasions, before Gianluigi Donnarumma fully stretched to parry Benjamin Pavard’s header in the 64th.
Mbappe had little to offer until the 74th, when he was denied from close range by Yann Sommer and had a goal ruled out for offside.
He found the back of the net again seven minutes from time but again was denied the equaliser for an offside.
With Mbappe initially on the bench but Messi and Marco Verratti back in the starting line-up following injuries, the 16-year-old Warren Zaire-Emery, on the right wing of a 4-4-2 designed to strengthen the midfield, became the youngest player to start a Champions League knockout game.
PSG took the first punches but threatened on the break in an intense, yet uneventful, first half, and simply waited for some Neymar or Messi magic.
Bayern were far from impressive either, with their only clear chance coming in the 43rd minute when Joshua Kimmich’s 20-metre attempt was blocked by Donnarumma
Bayern scored eight minutes into the second half when Coman latched on to a cross from Alphonso Davies, giving the visitors a deserved advantage that they held on to despite losing Pavard to a red card in stoppage time.
Bayern Munich play three games before the second leg at the Allianz Arena. Julian Nagelsmann’s side go to Borussia Moenchengladbach on Saturday, host Union Berlin on February 26 and travel to VfB Stuttgart on March 4.
Paris Saint-Germain also have three games before the return fixture in Germany. They host Lille and Nantes at the Parc des Princes, either side of a big away trip to Marseille on February 26.
