BORUSSIA DORTMUND fans' tifo was set alight before the Champions League semi-final at PSG.

The German side traveled to the French capital with a 1-0 lead from the first leg thanks to Niclas Fullkrug's winner.

The atmosphere was raucous inside the Parc des Princes with the visiting fans from Germany making their voices heard.

And they draped their famous club tifo over the away stands.

But local media say flares thrown from the PSG fans caught the banner and set it alight.

Pictures revealed the flares catching the tifo and the subsequently catching fire.

But Dortmund got the last laugh after winning 1-0 on the night thanks to Mats Hummels' header to make it 2-0 overall.

They now await either Real Madrid or Bayern Munich - who are level at 2-2 - in the final at Wembley on June 1.

Dortmund lost their last Champions League final to Bayern a decade ago... at Wembley.

And Marco Reus told DAZN: "Indescribable. After more than ten years, I am in the final with Borussia again.

"Ousmane [Dembele] and Achraf [Hakimi] brought a tremendous amount of pace and we suffered a lot.

"How we won the game, no one will ask tomorrow. Shots against the post won’t matter tomorrow.

"What counts is that Borussia Dortmund are in the final again. Nobody expected this. It's just incredible."
