Koscielny happy with first season at Arsenal
Koscielny has coped admirably with the step up in class from Ligue 1 to the English top flight and life has been good on and off the pitch.
"Everything is going very well," he told the Official Arsenal Matchday Programme.
"Off the pitch, my wife and I are delighted with our life here and the arrival of our baby. We are preparing everything and we are looking forward to it.
"On the pitch, in the last two months, I have been feeling very good. I am playing at my best. I am more confident and I have realised that I have the ability to become a regular player here and do well for this club.
"Before that, I had to adapt to a different style of football, with more duels, more rhythm. It was not easy but I got a lot of games under my belt, learnt from them, took a lot of experience and now I am feeling really good.
"I am also very grateful to the fans too who have always supported me since joining the Club. Their support was a big help for me."
