The Foxes parted with a club record £25 million to secure the services of the highly-rated youngster from Manchester City. But the Super Eagle has found opportunities hard to come by, featuring in only 12 games this season.
On Saturday, in Leicester's goalless stalemate to Fleetwood Town, despite an injury to first choice Jamie Vardy, the 21-year-old was again overlooked in favour of Islam Slimani whom he replaced with ten minutes left.
And while analysing the state of his current strikers, the Frenchman admitted that Iheancho - who is below Vardy, Okazaki and now, Slimani - must sit up.
“Slimani played well in the last game,” Puel said.
“It was a possibility for him to have another game or so, because he hasn’t played a lot, because of the injury to Jamie.
“It was a chance to see him again.
“We don’t have a lot of opportunities for all the players, like Ahmed Musa. It is just a choice.
“I think Kelechi is a young player and he needs to improve aspects of his play.
“Also it is difficult because he is a player behind Jamie Vardy and it means he doesn’t get many opportunities.
“Shinji Okazaki is also playing well, so it is difficult for him.
“He works hard on the pitch and in the training sessions and he needs to continue.
“I hope he can have some game time in the future," he concluded.
