Nigeria international Kelechi Iheanacho has signed a two-year contract extension with Manchester City that will keep him at the Etihad Stadium until 2021, the Premier League club said on Thursday.

The 19-year-old striker made his Premier League debut last season, scoring 14 goals in 35 appearances for City in all competitions.

“Kelechi is a natural goalscorer. I knew about him before, but I’ve been really impressed with him since I arrived,” City manager Pep Guardiola told the club’s website.

“I like his personality, his attitude, his ability — we hope to help him reach the highest level and to realise his full potential.”

Iheanacho came on as a second-half substitute in City’s 2-1 win over Sunderland in their Premier League opener at the weekend.
