Arsenal defender Calum Chambers is proud of his Champions League debut this week.
Chambers was again impressive in the 0-0 draw at Besiktas.
Chambers told arsenal.com: "It's a fantastic experience for me at a stadium like that and a crowd like that.
"All the boys put in such a good effort and I think we deserved a 0-0, if not more.
"You've just got to stay switched on the whole time and stay focused for 90 minutes. At any time they can create chances and score. It's another good experience for me playing against players of such quality.
"I've been working my way into Arsenal really well. That's helped my confidence. I've dropped into centre back and I'm really enjoying it there.
"You learn from playing and training every day with players of this quality. It's fantastic for me, and I'm gaining confidence game by game."
