Monaco have edged into the semi-finals of the Coupe de la Ligue with a 2-0 win at home to 10-man Guingamp.
The hosts took the lead with just eight minutes played when Dimitar Berbatov headed in at the back post from Yannick Ferreira Carrasco's cross.
Guingamp's evening got worse 10 minutes before the break as Christophe Mandanne was shown a red card for shoving an opponent.
The hosts created plenty of chances during the second half, but some poor finishing in the final third allowed the visitors to remain in the match.
However, Leonardo Jardim's side managed to seal their progress deep in added time thanks to Anthony Martial's strike.
