Mbappe, Falcao send Monaco into semis
Monaco were rewarded for a classy display as goals from Kylian Mbappe, Radamel Falcao and Valere Germain secured a 3-1 win over Borussia Dortmund and a place in the Champions League semi-finals.
Teenage France striker Mbappe showed why he is one of the most sought after talents in European football by scoring twice in last week's 3-2 victory at Signal Iduna Park, a match that was postponed by a day following an attack on Dortmund's team bus that left defender Marc Bartra hospitalised.
And it took just three minutes of this second-leg encounter for Mbappe to pounce on a Roman Burki error at Stade Louis II to become the first player to score in his first four knockout-stage appearances.
That set the tone for an enthralling first half, and Dortmund were further up against it when Radamel Falcao headed in his 45th goal in 50 UEFA appearances from a sublime team move.
Marco Reus, who missed the first leg with a thigh injury, swept home shortly after half-time as Dortmund threatened a fightback.
But Monaco ensured there was no way back when substitute Valere Germain scored with his first touch with eight minutes remaining to secure a 6-3 aggregate win.
There will be sympathy for Dortmund, whose coach Thomas Tuchel claimed it was "absurd" to play last week's first leg so soon after the incident with the team bus, and they will wonder what might have been had Nuri Sahin's free-kick not rebounded off the post with the score at 1-0 here.
For Monaco, the result means they reach the last four for the first time since their run to the 2003-04 final and the youth, vibrancy and pace they possess in abundance mean's Leonardo Jardim's men will be a threat to Real Madrid, Juventus or Atletico Madrid.
A five-minute delay to kick-off due to Dortmund - with whom Bartra travelled to the game - being held up in heavy traffic only stalled Monaco's lightning start.
Benjamin Mendy's long-range effort had plenty of swerve but was poorly parried by Burki and Mbappe was typically quick to coolly slot home the rebound.
