Iheanacho joined the Cityzens in 2013 after his nation's national side won the FIFA Under-17 World Cup.
Iheanacho's transfer price was revealed to be £250,000 (€300,000), with another £300,000 (€360,000) going to the Taye Academy in Owerri and £350,000 (€420,000) going to his father.
Iheanacho's situation was improving under Manuel Pellegrini, but everything changed drastically when Pep Guardiola took over in 2015.
Iheanacho backed up Gabriel Jesus and Sergio Aguero before signing to Leicester City for £25 million in 2017.
“Obviously, I didn’t get to play much but I was part of a big squad with brilliant players to win that It was exciting.
“There were a lot of them (quality players). Yaya Toure, Samir Nasri, Jesus Navas, David Silva and Vincent Kompany, who always talked to me and gave me advice,” he revealed.
The Nigerian international scored 21 times in 64 games for Manchester City, and he brought some of those experiences and lessons with him to King Power Stadium.
Iheanacho said, “Gael Clichy, I called him my teacher.”
“He’s the one who taught me how to go and get what you want and how to be tough and fight on the pitch, because he is a fighter. He never gets tired.
“He was always with me and pushing me. If he was against me (in training), he was going to kick me and say that I have to stand and fight back. I will never forget his kind words and teaching. He was my closest friend,” he stated.
