N'Zogbia has been largely disappointing since signing for Villa in 2011, but has recently shown a marked improvement to earn a regular place in Paul Lambert's side.
He told The Sun: "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."
