The 27-year-old former painter and decorator - who was crowned winner of the ITV1 show on Sunday (12.12.10) - admitted while his £1 million recording contract prize will change his life for the better, he also wants to have a career that justifies his win.
He explained: "Everyone who has voted for me has turned my life inside out and upside down in a good way, hopefully. I want to go on and have a career that justifies me winning the show.

"It was just some confirmation that everything I've been working so hard at for the last 12 years has been worth it. If you've got a dream, chase it down and don't let anyone tell you you can't do it. If you believe in yourself you always can."
Meanwhile, fellow contestant Mary Byrne - who finished in fifth place in the competition - revealed she always expected the Essex-based hunk to win the show.
She said: "Right from the beginning, I always knew Matt would win. He deserves it and he really is a lovely guy."
