He is excited about linking up with £35million new-boy Aguero, who is set to make his bow at Wembley after arriving from Atletico Madrid.
Former Barcelona ace Toure played against the Argentine striker while they were both in Spain and believes City fans are in for a treat.
He said: "The club are signing players and we are getting some good, important players returning to their best. Edin Dzeko is in good form and we have signed Aguero, so we're getting better and better.
"Aguero is a fantastic player. He is so smart, so clever. He is very, very fast.
"But you look through the squad and there is real quality in all positions - not just the starting 11 but on the bench too."
