Monaco coach Thierry Henry conceded his side did not do enough to beat 10-man Nice as he met former team-mate Patrick Vieira in the Cote D'Azur derby.
Henry's side remain without a home win in Ligue 1 and sit 19th in the table as teenage defender Benoit Badiashile's header earned Monaco a 1-1 draw.
Allan Saint-Maximin had opened the scoring for Nice, who had Ihsan Sacko sent off on the stroke of half-time with the aid of the video assistant referee.
Despite being outnumbered, Vieira saw his side win a late penalty only for Saint-Maximin's effort to be saved.
Monaco hit the post through substitute Radamel Falacao late on but Henry admitted that his side were found wanting when they had an advantage.
"We did not do enough," he said.
"One point is not enough. We had the opportunity to score but we didn't – it is not the first time.
"We woke up in the second half but they had 10 men. It is never easy to play against a team that is outnumbered."
Asked about coming up against his former Arsenal and France colleague Vieira for the first time as a manager, Henry added: "It was weird to meet Pat (Vieira) before the match, during and at the end.
"We spoke a little but then we were each focused in our game, in what we had to do."
Henry was unable to call on another former Arsenal man in Cesc Fabregas – one of four January signing deemed ineligible as the fixture was rescheduled from December.
Vieira, meanwhile, did not call on the services of striker Mario Balotelli with the Italy international set to depart during the transfer window.
Nice missed out on the chance to move up to sixth with a win at the Stade Louis II but Vieira was left bemoaning Sacko's dismissal.
"There is a lot of frustration and questions also to be asked of the referee," he said.
"The red card for Sacko is extremely harsh. I don't understand it. I have watched it back and I don't think that it is dangerous.
"This red card had a big impact on us. At eleven against eleven, we would have been much better.
"We didn't win. It is still a good point away from home, against a side in trouble and who really needed to win."
