Les Gones have now lost successive Ligue 1 outings, having fallen to a 3-1 loss at the hands of Bordeaux prior to this weekend’s 3-2 defeat to Monaco.
Lyon led 2-0 inside half an hour but they were pegged back and went in at half-time all square at 2-2, although Monaco were reduced to 10 men when Balde Keita was shown a second yellow card.
The French duo battled out an entertaining second period and the clash was eventually decided with just two minutes left to play when Ronny Lopes bagged the winner for the defending champions.
Aulas revealed his disappointment at the final result but has called on the players to dust themselves down and get back on track when they face Montpellier in the Coupe de France on Wednesday.
“It’s very disappointing. Everything was in our favor for us to win, with [Danijel] Subasic and [Radamel] Falcao leaving the game with injuries and [Keita] Baldé being sent off,” Aulas said.
“I’m the first to cheer on the players, but tonight they need to ask themselves: Have we been overconfident? We must put aside these two defeats against Bordeaux and Monaco to get back into a positive streak.”
