The Frenchman, who rejoined Arsenal on a free during the summer after five years at AC Milan, insists that he is happy with life at the league leaders.
"It is going well for me on and off the pitch. We are doing well, so I'm delighted," Flamini told the press. "We knew that Napoli are a good team who are doing well in the league with excellent players. But we had an excellent match and managed to score those two goals.
"In Italy the football is different, more closed tactically, whereas here it is more open, plus we have a very good team. I play defensive midfield here and have to protect the defence and it is going well.
"I wanted to play in a different championship and play with great players such as [Paolo] Maldini and other European and world champions. I won the league [in Italy with AC Milan], but then I came back to my old team and I'm happy with that."
Arsenal travel to West Bromwich Albion on Sunday.
