Nice won in Reims to reach the last-four...
Danijel Ljuboja gave Nice the lead just a minute after the half-hour mark but inside seconds Reims equalised through Romain Amalfitano.
Just two minutes into the second-half Eric Mouloungui gave the visitors the advantage again, and this time it lasted just 11 minutes when Odaïr Fortes restored parity.
The game went into extra-time after neither of the two sides failed to score in the remainder of the 90-minute period.
Then in the 113th minute Mouloungui scored his second of the evening to book a place for Nice in the semi-finals.
