France drew 0-0 with Switzerland but were mere centimetres away from victory as they hit the woodwork three times, while opposing goalkeeper Yann Sommer produced three superb saves.
“If the goalkeeper is man of the match it really tells you how it went,” Deschamps said, adding he had wanted a third win, but was content to have topped Group A.
By doing so, the hosts have earned an extra day’s rest over coming second, with a last-16 match against a third-place finisher in Lyon on Sunday.
“We’re pretty relaxed. I think we’ll find out on Tuesday, definitely by Wednesday, who we’ll face. But we have a long rest ahead,” Deschamps said.
The France coach said he had stabilised a defence which had come under scrutiny after letting in two goals in friendlies against Cameroon, Netherlands and England and four a year ago versus Belgium, but his players now needed to be more clinical.
“In a short space of time we have resolved things defensively, from set pieces,” he said. “Now a second competition is starting, in which we need to step up a gear.”
Deschamps added that France could do better in controlling games and also in attack, for example by becoming more threatening from corners.
“We need to be able to mix things up too. Some (corners) we hit a bit too high, some to the same area. Perhaps we didn’t have the right running position. These are things we can tweak,” he said.
