Iheanacho scored twice in the FA Cup replay victory over Fleetwood Town this week.
He said: “The first part of the season is gone and it is the second part now. I am happy to get the two goals and now hope to progress in the future.
“It gives me more confidence to play well, get back in the team and help them achieve great things in the future. As a footballer, you need to keep working hard through the bad times and the good times.
“If the chance comes, you take it. When I first arrived, I got a toe injury in the last pre-season game. That slowed things down a little bit and I am happy I am getting to come back.
"I am feeling better, stronger and working hard in training every day to progress. I hope I will have a very successful and injury-free second part of the season.
“I am fit now and confident. We have so many more games to come and I will keep working hard to help the team.
“The fans have seen a bit of me, I hope to continue like that in the future and in the games to come."
