Leicester City striker David Nugent is determined to prove himself Premier League class.
Nugent previously scored just nine goals in three seasons in the Premier League with Portsmouth and a loan spell at Burnley.
But he has been flying in preseason and told The Independent: "It didn't happen for me at Portsmouth, maybe it wasn't the right club for me.
"But everybody makes mistakes in life and I'm fitter, stronger, older, wiser and I'm ready for the Premier League this season.
"I have unfinished business. I think people still believe I'm not good enough for the Premier League but I'm going to prove them wrong."
