The 28-year-old will cost City around £15million and will have a medical in Manchester today.
Arsenal boss Arsene Wenger said: “We will see what’s happening in the next 24 hours, nothing is decided yet.
“We have seven centre-backs and I am in the position where I have to play some in midfield but of course Kolo is a very good player and we will see what will happen in the next 24 hours.”
