Sagna will face former Arsenal team-mates Gael Clichy, Samir Nasri and Kolo Toure when the Gunners face City on Sunday.
Sagna told The Mirror: “You know, even when I see Gael play now for City, it is strange but I still see him as an Arsenal player!
“But they all left and there is no problem for me that they did.
“I mean, they had just one year left on their contracts and they wanted to be part of the project at Manchester City.
“That was their choice. Usually, when someone rich buys a club there is no big ethic. But I think it is different there.”
“I am very happy here,” continued Sagna.
“Everyone is so close. Yes, I would be happy to stay even longer but to be honest I don’t think that far ahead. If it happens, it happens. I just want to stay part of this Arsenal squad.
“We have a great team, a young team. And the spirit here is great. We have shown that recently with the way we got into the top four when we were so far behind.
“Yes, we lost at Queens Park Rangers in our last game but the simple fact is they fought harder than us. It was a good wake-up call.”
