The Nigeria international has completed a permanent switch to the King Power Stadium in a deal worth a reported £25m, although Man City do have a buy-back clause in the contract for £50m.
The 20-year-old striker had fallen down the pecking order at the Etihad Stadium following Pep Guardiola’s arrival, with Sergio Aguero and Gabriel Jesus preferred to him.
“It feels good and I’m happy to be part of this team. I know the ambition of the team and speaking with the manager, he let me know what I need to do – to help the team achieve what they want. I was convinced and I’m happy to be here,” Iheanacho told the club’s official website.
“I was happy speaking with the manager, knowing what the team wants. It gives me more confidence that I will fit in this team and hopefully I’ll achieve a lot.”
Iheanacho, who will wear the number eight shirt for the Foxes, could make his debut in the opening match of the new Premier League season when Leicester take on Arsenal next Friday.
