Toure feels Mancini relaunched his career after playing as a defensive midfielder with Barcelona.
He told Izvestia: "I worked with Mancini for two years and I can say that he is a top manager. He always trusted me and had a great influence on my development.
"When I started playing for the Italian, he moved me closer to the attack, raised my standards. For this I am very grateful to him.
"We won the championship of England, but failure in the Champions League hurt our work.
"I want to wish every success to Roberto with Galatasaray."
