The Italian coach was not impressed with his men's display as he feels they made too many mistakes and were fortunate to bag the full three points
Claudio Ranieri has voiced his anger with Monaco's performance during their 1-0 win over Lorient at the weekend and has insisted that they must improve if they are to challenge for silverware this campaign.
The Ligue 1 newcomers made it four wins from five matches thanks to Radamel Falcao's sixth-minute penalty at the Stade Louis II, but the former Juventus boss lamented the number of mistakes his side made during the clash.
"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," the Italian said at a press conference.
"It was important to have the possession of the ball. We won 1-0 but they did create many chances, it was a tight game."
Ranieri believes his side made life difficult for themselves during the clash, citing a Falcao chance that was not taken in the second half as a missed opportunity.
"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."
Monaco face champions Paris Saint-Germain at the Parc des Princes in their next Ligue 1 fixture on Sunday.
