If Marc McCullough is to land the Irish featherweight title then he is going to have to walk through the hardest punches he has ever had to handle, according to Limerick's Willie Casey.
Former European super-bantamweight champion Casey admits that he is facing a make-or-break night at the Odyssey on Saturday but is adamant that his career will be moving forward at the expense of young McCullough.
Since winning the European title in 2010 and then losing to Guillermo Rigondeaux in a World title fight in 2011, southpaw Casey has lost a WBA international featherweight title fight and then in July last year he lifted the WBA European super-bantam belt.
But the 15 months out of the ring since that victory over Jason Booth has left Casey's career in a little bit of limbo.
Consequently, the 31-year-old now views a victory over McCullough as crucial.
"I think I will have too much aggression and power for Marc. I think he might be shocked by the power," said Casey.
"He has the advantage in height but I can match anyone for strength. We have sparred before but there's a big difference between the big gloves and the small ones in a fight.
"There is pressure on me because this is an opportunity I have to take. When I beat Booth I went into the WBA ratings but because I have been inactive I have dropped out of them.
"If I get a good win over Marc it could open more doors. This is very big for me.
"And I have been there and done it before, I have more experience – I have the rounds under my belt and I think that will count for a lot. He's the up and coming guy and he will have a lot to prove but so do I. I have to get my career going again and I believe that I will have the edge on the night."
