After a difficult season and a half, he has begun to show some signs of form under boss Paul Lambert.
The Frenchman said: "You can have a gift but if you don't work on it you can do nothing with it. If I've improved it's because of the way I am training.
"Every day I'm here I'm working hard because if I want to stay in the team that's what I have to do. I'm even doing a bit of extra work after training and it is helping me."
