Not even Kylian Mbappé's substitute appearance could stop Paris Saint-Germain's slump, as it lost 1-0 at home to Bayern Munich on Tuesday in the first leg of their round-of-16 Champions League clash.

A third straight loss made it five defeats in 11 games this year for PSG coach Christophe Galtier’s team, AP reports.

Bayern winger Kingsley Coman volleyed home inside the penalty area from Alphonso Davies’ left-wing cross in the 53rd minute.

The Paris-raised Coman, who PSG sold to Juventus when he was 18, held his hands up to show he wasn’t celebrating scoring against his former club — again.

When Bayern won the last of its six Champions League titles in 2020, it beat PSG 1-0 with Coman heading home the winner.

The World Cup superstar Mbappé made an unexpectedly quick recovery from injury and had two would-be goals disallowed for offside after coming on in the second half.

“It was difficult, unpredictable. I wasn’t supposed to play but I wanted to play and help my mates. We did everything, we worked night and day to get me some game time,” Mbappé said. “I wanted to (start the game). But sometimes you have to be satisfied with what you can do, and that’s all I could do.”

The return leg is on March 8.
