Teenage sensation Kylian Mbappe scored again to set Monaco on their way to a 3-1 second-leg victory over Borussia Dortmund on Wednesday that allowed them to win their Champions League quarter-final 6-3 on aggregate. 

Radamel Falcao also netted for the home side in a whirlwind start at the Stade Louis II, and Dortmund were left with too much to do to save the tie. 

Their skipper Marco Reus pulled a goal back early in the second half but Valere Germain came off the bench to put the seal on a famous win for a brilliant young Monaco side, who go through to the last four for the first time since 2004.

Meanwhile, Dortmund bow out after a tie overshadowed by the bomb attack on the team's bus last week that forced the first leg to be postponed by a day.

The Germans lost that match 3-2, their minds elsewhere, but their hopes of turning the tie around in the second leg were not helped when their bus was held up on the way to the Stade Louis II, leading to a five-minute delay to the kick-off.

UEFA blamed "heavy traffic" for the hold-up but, on their official Twitter account, Dortmund said they had been delayed in leaving their hotel by police for around 20 minutes "without justification".

"It was the worst thing that could happen a week after the attack -- everyone was on the bus ready to go but we were not allowed to," Tuchel said.

While the appearance of Spanish defender Marc Bartra -- who needed surgery for a broken wrist suffered in last week's attack -- at the stadium was a boost to Dortmund, the delay unsettled Thomas Tuchel's side and their hopes were effectively ended in a terrible opening 20 minutes.

Barca done and dusted

A distraught Neymar left the field in tears as Juventus held Barcelona to a 0-0 draw at the Camp Nou on Wednesday to reach the Champions League semi-finals 3-0 on aggregate.

Barca had overcome a 4-0 first-leg deficit against Paris Saint-Germain in the last 16 with a dramatic 6-1 win back on home soil.

But Juventus showed why they boast the best defensive record in the competition as Lionel Messi, Luis Suarez and Neymar were blunted as the Italians gained revenge for their defeat in the 2015 Champions League final.

"To not concede a goal in two games against Barcelona says a lot about the tactical level of the team," said Juventus boss Massimiliano Allegri.

Allegri's men pressed high to prevent Barca dominating possession and enjoyed the better of the early chances.

Barca had to wait 19 minutes for their first clear sight of goal as they intricately worked the ball around a packed Juventus box before Messi fired inches wide.

Messi then stung Gianluigi Buffon's palms for the first time on the half-hour mark.

"Overall they were the better team and deserved to go through," Pique told BeIN Sports Spain.

"Little-by-little we started to create chances, but they built a mountain."

Messi had another big chance after a rare Buffon handling error from a corner, but unfortunately for Barca it fell on his right foot and the Argentine fired well over.

Juventus comfortably saw out the final stages to register their eighth clean sheet in 10 Champions League games this season.
