Monaco returns home on Wednesday in the Champions League quarterfinals for its second-leg clash against Borussia Dortmund after last week's brilliant 3-2 win on the road.
Attacking midfielder Marco Reus pulled one back in the 48th minute, but substitute Valere Germain added the third in the 81st minute to seal a 6-3 victory on aggregate.
Only Barcelona and Bayern Munich (4) have been awarded more penalties than Monaco (3) in this season's Champions League. "We knew that they give a lot of space and we took advantage from it". We'll try to be flat out in the Champions League and the league, but it's normal that we're more exhausted than teams who play less. It was going to be hard getting back to business as usual but the team should first simply enjoy playing football which would be the best the team could achieve under the circumstances.
Dortmund coach Thomas Tuchel accepted that his side fell short. "That would be a huge influx of energy", said Tuchel. "It was a very hard situation for the players so we should not criticize them too much".
An early goal would have been the one thing Thomas Tuchel wanted to avoid, but the breathtakingly talented Kylian Mbappe put the home side in front after just two minutes.
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. Kickoff was briefly delayed.
Dortmund made the worst possible start to the match, conceding a goal after just three minutes.
Attack-minded left back Bernard Mendy - newly called up to the France team along with Mbappe - hit a fierce shot that goalkeeper Roman Burki spilled.
But Mbappe was always looking to break on the counter, though it was Falcao who should have killed the tie off in the 65th minute, but he failed to repeat the wonderful "dink" he scored at Manchester City in the round of 16, when given plenty of time and space.
But any hopes they had learnt their lesson disappeared in last week's first leg in Turin where Juventus ran out deserved 3-0 winners and Messi was largely anonymous.
Raul, a three-time Champions League victor with Real Madrid, was 41 days older than Mbappe when the Spaniard scored his fifth goal in the competition.
Before kick-off, the home fans showed solidarity by unveiling a banner which read: "BVB: You Will Never Walk Alone" as the anthem played out around the Stade Louis II. Mbappe also blew his own chance to book a place in the last four when blazing between Dortmund lines in an inside-right position.
