Paris Saint-Germain's wait for a Champions League title may drag on for yet another season.

The newly crowned Ligue 1 champions fell 1-0 to Borussia Dortmund in the first leg of their semifinal clash Wednesday. Niclas Füllkrug's goal in the 36th minute was the difference in the match.

Given the sheer amount of talent on display, plenty of fans expected a prominent attacker to take center stage at Signal Iduna Park; Jadon Sancho wouldn't have been high on the list, though.

Maybe the 24-year-old simply loves putting on a Dortmund shirt. The commanding performance he delivered on the right flank was a common sight during his first spell in Germany and has been decidedly lacking following his move to Manchester United.

It was a tougher night for the player Sancho helped to replace years ago. Ousmane Dembélé had an opportunity to deal a major blow to his old club as PSG searched for an equalizer deep into the second half.

Instead, he skied his effort from inside the 18-yard box over the bar in the 81st minute.

It was that kind of night for Paris Saint-Germain, which collectively lacked the finishing touch.

Perhaps no club has been more synonymous with heartbreak and disappointment on the European stage than PSG over the last decade. The Parisians have spared no expense in pursuit of a winner's medal since Qatar Sports Investments executed its takeover in 2011, and they've largely succeeded only in becoming a running joke.

That Paris Saint-Germain couldn't secure a draw, even away from home, against the fifth-best team in the Bundesliga is a result that will lead a lot of world football fans to believe we know how this story is going to end in the return fixture.

The second leg will get underway at Parc des Princes on May 7.

Nobody should count out PSG considering this isn't even the worst position it has found itself in heading home in the second half of a knockout tie. The postmortems were probably being written the moment Raphinha put Barcelona ahead 4-2 on aggregate in the quarterfinals. Then Paris Saint-Germain scored four unanswered goals.

One thing is clear: Lady luck will need to shine on Luis Enrique's squad a lot more than it did Wednesday night for the turnaround to happen.
