Brown is pleased with his current form and insists he's only thinking about success with the Hatters.
He told The Sun: "In my head, I think I can play in the Premier League.
"I don't think that's big headed because I have been there before and I don't think I was out of my limits. But with my injuries I took two steps back when I was on my way up.
"When I am on the pitch, I do feel like you can't tackle me. I am going to run over you in this game. You are not going to get close to me. If it is me against you then I am going to beat you.
"When you go into a game with that mentality, you are already a step. You're not arrogant. You are confident."
He added: "I am not focused on the Premier League at the moment.
"I think everyone has a different path. You can have your moment when you are 18 or 25. There's no age limit.
"I know that when my time comes, I am going to be ready to take it."
