Europa league giroud gives arsenal victory
I think there may be some confusion here!
Olivier Giroud is a French professional footballer who plays as a striker for Chelsea FC, not Arsenal FC. He has played for Arsenal in the past, but he is currently playing for Chelsea.
If you're thinking of a specific Europa League match where Giroud scored a goal to give Arsenal a victory, I'd be happy to try and help you identify the match. However, I should note that Giroud has never played for Arsenal in the Europa League, as he left the club in 2018 to join Chelsea.
If you could provide more information or context about the match you're thinking of, I'd be happy to try and help you out!
