It will be the first time Toure has faced his former club.
He told City's website: "It's going to be a good game. We have a good team and the quality to get a good result but we know it will be difficult. Barca are very strong both physically and tactically but we will try our best.
"I moved to City to win things and have won some trophies already and many personal awards so when people ask was it right to come here from Barcelona I say absolutely. I'm very happy and hope that we continue to win titles.
"It was the right time for me to leave Barcelona and I have nothing to prove to them. We are trying to make history at City and the future is very exciting and I hope I'm here for a long time."
