Borussia Dortmund coach Thomas Tuchel revealed his team watched the end of Barcelona's epic win over Paris Saint-Germain in a "party mood".
Tuchel's side had claimed a memorable win of their own - beating Benfica 4-0 to reach the Champions League quarter-finals - before seeing Barca complete a remarkable comeback.
The LaLiga giants overturned a 4-0 first-leg deficit, beating PSG 6-1 on Wednesday to win 6-5 on aggregate.
It came after a late brace from Neymar and a dramatic 95th-minute goal from Sergi Roberto at Camp Nou.
Tuchel said Dortmund caught the end of the encounter, which he felt made his team's win look dull.
"We were ecstatic when we came into the dressing room, after the 4-0 on the pitch," he said.
"I thought it was 4-1 at the time [at Barcelona-PSG] but it was 5-1 with two minutes to go.
"We all stood there like we were involved ourselves, all in a party mood. We followed the closing minutes over the TV.
"Suddenly, everybody who came in joined us and watched. Everybody had the feeling that Barca would score one more.
"When it happened, it was insane. We thought before that we would be the exciting news, but compared to that we were boring.
"If anyone can do it, it is Barcelona. Congratulations for this extraordinary performance."
Pierre-Emerick Aubameyang was the hero for Dortmund, his hat-trick leading Tuchel's side to their second-leg win at Signal Iduna Park.
