Debuchy: Giroud right to leave Arsenal for Chelsea
St Etienne signing Mathieu Debuchy can understand former Arsenal teammate Olivier Giroud joining Chelsea.
Both former Gunners quit the North Londoners on deadline day.
Debuchy declared: "Olivier, he was a close friend. There has been a lot of talk lately. I think he chose the right option.
"It's him who feels it like that, it's him who decides. He wanted to stay in the English league. I do not worry too much about him. He's someone who always manages to score goals, and he does it very well."
