Sagna left the Gunners for City earlier this summer.
"It wonâ€™t hurt me," he said. "Iâ€™m ready to expect anything now.
"Itâ€™s not easy to read some comments on social networks. I know itâ€™s only a small minority and not all the Arsenal fans, but itâ€™s still not easy to read it because I feel I gave everything.
"If I was the first one then okay, but I donâ€™t know what to think. Every time a player leaves they seem to get abuse. There are so many on social networks but that doesnâ€™t represent the whole Arsenal family.
"To me, I made the right choice and Iâ€™m very happy to be here, no matter what they think. Iâ€™m not the first one to leave their club and I wonâ€™t be the last one.
"Iâ€™m looking at my personal life now and I want to fight, get in the team and give the maximum. I donâ€™t look at the negatives."
