Wilson, 23, was released by Manchester United over the summer.
He told the the Daily Mail: "I'd like to think I've not hit my peak yet, so I'm working towards that (getting back to the Premier League).
"I'm coming in every day trying to make myself a better player, a better person, and, if it doesn't work out, it doesn't work out.
"That's just the way football goes but I'm certainly going to do everything I can within my power to make it happen."
