The South Korean has scored against Bolton in the Carling Cup but failed to impress in the Champions League against Marseille.
“I couldn’t train much for about two months before I moved here”, the Korean told Arsenal’s official website.
“I just had to do some personal training instead.
“Since I joined the team it has been two months and I feel like I am in my normal condition now. The coaches adjust the training depending on the games we play and it’s good.”
