The 24-year-old has arguably adapted to the unique demands of the Premier League better than any Arsenal foreign signing - and there have been many - since Patrick Vieira.
"It was not a big transfer by today's standards but he's shown that he can be a big player. He has impressed everyone with his quality and enthusiasm.
"He has huge potential and can play in several positions. What I like is that he's arrived here and adapted to new challenges with the minimum of fuss."
Sagna credits pre-season for putting him at ease in his new environment.
"Every day in the training camp in Austria I felt I got better and I started to play in the strongest side in the games we had over there," he said.
"Then I was given the chance to start the season and we won the games, so it's good for me."
