The Nigeria international has surpassed his previous record of eight goals in a league season which was achieved after 26 matches in the 2015-16 campaign at Manchester City.
After grabbing the match-winning effort that sent Leicester City into the FA Cup final on Sunday, the 24-year-old continued his goalscoring form as the Foxes bounced back to winning ways in the English top-flight on Thursday night.
In the 36th minute, Iheanacho compounded West Brom’s woes after combining with Vardy to complete their first-half dominance and end their back-to-back defeats in the league.
The effort also took the Super Eagles striker’s tally to 13 goals in all competitions in 2021, making him the second-highest scorer for a Premier League club after Tottenham Hotspur’s Harry Kane with 15 goals so far since the start of the year.
Across all competitions, Iheanacho has scored 16 goals for the Foxes – nine in the Premier League with three and four goals in the Uefa Europa League and the FA Cup, respectively.
Next up for Iheanacho and Ndidi’s Leicester City is a Premier League fixture against Crystal Palace at the King Power Stadium on Monday with the former aiming to better Odion Ighalo’s record of 17 goals in a single campaign.
