Despite heading into the tournament as favourites, France failed to convince fans in their group stage matches, finishing in second spot below Austria.
France began their campaign with a 1-0 victory over Austria that came courtesy of an own goal, before they drew a blank in a 0-0 draw with the Netherlands.
Needing a win to secure first spot in their final group stage match, France played out a 1-1 draw with Poland in which Kylian Mbappé scored with a penalty.
Their lack of goals is a concern for Deschamps, who hopes they can rediscover the impressive scoring form they showed in qualifying.
“We need to score more goals, we need to be more clinical, and I am looking for that,” Deschamps told reporters. “We can improve but that’s it. We need to hit them where it hurts but we have always had a goal average that is quite impressive, for these three games it hasn’t quite been there.
“But I am positive, I am always positive. It is a new competition starting for us.”
Deschamps also spoke about Mbappe who got his first European Championship goal as he made his return to the France side wearing a face mask after breaking his nose in their opener against Austria.
Deschamps said it was important for Mbappé to get back into action though, wearing a mask is causing the France captain some issues.
“I thought he was quite good on his feet, with the mask he had to get used to it even though when he sweats it stings in his eyes and he needs to wipe his eyes,” Deschamps said.
“But he is hungry to play and the game will have done him some good.”
France had 19 shots in the game but could not find a way past Poland keeper Lukasz Skorupski who was named man-of-the-match from open play.
“No I am not disappointed, honestly,” Deschamps said. “Some times we weren’t accurate enough. We gave everything we had until the very end.
“We do have a lot of chances. But it’s not just about us not being accurate enough or getting shots on target.
“You also need to give credit where credit’s due to the goalkeeper.”
