"I have to take a guy who has been ranked as high as six in the world ratings and who would have thought it?

Rogan trains out of Breen's gym in central Belfast while former Commonwealth light-welterweight champion Magee has become an increasingly important part of Team Rogan.
The Commonwealth title challenger says he and his handlers have developed a tactical strategy which will outwit Skelton, whose 22-2-0 record includes wins over Julius Francis, Danny Williams and Michael Sprott.
"I can't tell you any more than that or else I would have to shoot you," laughs Rogan.
"Skelton's a bull-like character as he comes forward and throws you about.
"If he wants a rough-and-tumble fight that's fine but there's a referee and he gets paid to do his job."
Skelton, who lost a world title challenge against WBA champion Ruslan Chagaev 14 months ago, claimed the European title when he stopped Italian Paolo Vidoz in December.
However, Skelton's European belt is not at stake in Saturday's contest.
