Woodhall makes the first defence of his title against Bristol's British middleweight champion, Glenn Catley, in Telford on Saturday, but knows that the big money will come from a clash with the Welshman, Calzaghe.
"That fight should be worth a million to each of us," said Woodhall. "That is what Calzaghe will also be thinking. It is at the back of my mind and is what I have got to be aiming for in the future. I have always said that I want to be a world champion and a millionaire in the process.
"But at the moment I cannot look too far ahead and I have got to deal with Catley first."
