Kelechi Iheanacho on Tuesday evening completed a £25million move from Manchester City to Leicester City after passing a medical, sources have confirmed to KweséESPN.
The fee makes him the most expensive Nigerian player ever, displacing Odion Ighalo when he signed for Chinese club Changchun Yatai for £20million in January.
It is also the second highest African transfer fee this season behind Mohammed Salah's £34.3million move from Roma to Liverpool.
The transfer, which has been in the offing for weeks, was held up by legal issues over his image rights with his former agents. But sources close to the player confirmed to KweséESPN that after passing his medical on Tuesday, the player signed a five-year contract with the Foxes.
However, an announcement is only expected within the next 24-48 hours as the club tidy up legal details in respect of his former representatives.
Manchester City have inserted a buy-back option in the contract, which KweséESPN is told has been pegged at £50million for one of Europe's brightest young footballers.
It is unlikely, but Iheanacho could be announced in time to be involved in Friday's friendly against Borussia Monchengladbach at the Kingpower Stadium.
Leicester's capture of the 20-year-old, who scored 26 goals in his 71 appearances across all competitions and friendlies for Manchester City, brings to three the number of Nigerians at the KingPower after Ahmed Musa and Wilfred Ndidi.
