Giroud was given just two minutes in the narrow friendly win over Portugal last week, and he was a big disappointment in his 62 minutes on the pitch against Serbia.
The striker only registered 16 touches on the ball before being substituted for Karim Benzema, with the Gunners man booed by the crowd as he left the pitch. Giroud had earlier spurned several chances, not to mention gifting possession in the build up to Serbia's goal.
But former World Cup winner Deschamps wasn't pointing fingers at the former Montpellier star.
"It's a collective effort and he [Giroud] contributed too," Deschamps is quoted by ESPN as telling the press after the match.
"He was unlucky as well because the keeper made a superb save. He had three chances with one shot off target and a header that went wide.
"Obviously if he was more efficient we would have been a lot further ahead but he put in a lot of effort.
"Olivier knows it -- he's the first to be sad about not being able to be effective but it happens."
It's Arsenal's problem too
Giroud has managed to get off the mark this season for his club, scoring the the Gunners' only Premier League strike that hasn't been an own goal when he netted the opener against Crystal Palace.
But the France international has struggled with his shooting and influencing of games at times, and Giroud was benched in favour of the Theo Walcott in the win over Newcastle United.
Walcott has had quite a different international break to the 28-year-old as well, coming off the bench against San Marino to remind everyone of his goalscoring prowess with an impressive brace, and the former Southampton could yet get a chance to impress in the game against Switzerland on Tuesday.
It could mean Arsene Wenger could continue with the England international in this weekend's home game with Stoke City.
