Monaco coach Claudio Ranieri has expressed his anger at his side's performance despite moving back to the top of Ligue 1 on Sunday.
Last season's Ligue 2 champions edged out Lorient 1-0 at the Stade Louis II thanks to an early Radamel Falcao penalty.
"I am a little bit angry as we made too many mistakes, we did not pay enough attention on our passing and didn't raise our game," Ranieri told reporters.
"It was important to have the possession of the ball. We won 1-0 against Lorient but they did create many chances, it was a tight game. We were in control for most of the game and in the end it was more complicated.
"I am satisfied with the way we played except for some bits during the first half. I think that Falcao had the opportunity to score the second goal. Lorient also had one or two opportunities to score thanks to [Yann] Jouffre."
Monaco travel to title rivals Paris Saint-Germain on Sunday.
