And the forward still looked to be devastated less than 24 hours after missing chances in Arsenal's draw with Tottenham.
Giroud had failed to hit the target with two close range efforts in the second half, and appeared visibly angry with himself for his misses.
When he arrived at Clarefontaine on Monday morning, he had the look of a man who had pitched up in France, only to remember he had left his oven on back in London.
Manchester United striker Anthony Martial appeared a lot more relaxed as he arrived, having helped his side to a victory over West Brom at the weekend.
That was nothing on former United man Patrice Evra, who looked like he did not have a care in the world as he sauntered up to the training base.
One player who appeared overjoyed to be there was former Newcastle United winger Hatem Ben Arfa.
After being loaned to Hull at the start of last season, and then released early in 2015, Ben Arfa has rebuilt his career having signed as a free agent with Nice.
The 28-year-old has been in phenomenal form, netting seven goals in his opening 10 games, earning a recall to the French international squad, and with Euro 2016 next summer, an unlikely redemption story is beginning to play out.
