Richards, 19, has missed two matches over the past week due to a knee niggle but is ready to face the Gunners, the club he supported as a youngster.
Having been linked with a move away from City, he insists his future is with the blue half of Manchester and signing a fresh deal is on the horizon.
He said: "I have got two-and-a-half years on my contract and I am not going anywhere. There is no timescale in my mind, just when it's ready to be signed it will be signed.
"I am 100 per cent going to sign for the club. There's nothing to worry about. Things don't happen overnight."
