Iheanacho continued with his fine goalscoring form on Sunday, April 18, 2021, when he scored the winning goal as Leicester City beat Southampton 1-0 in a semifinal clash of the FA Cup. 

After the game, Ndidi and Iheanacho are seen bantering in a dressing room video where he asked him the secret of his goalscoring form. 

 "Oh boy, who cut soap for you, I need that soap ooo," Ndidi says in the video, which in Nigerian context means 'what's the secret of your secret?" 

Bantering in response, Iheanacho went on to mention a slew of soap brands known in Nigeria. 

Iheanacho is in the best form of his career so far. He has 15 goals so far this season, his best season-tally of his career so far. 

On Sunday, his goal against Southampton took his FA Cup tally to 13, making him the highest-scoring African in the competition.
