Enzo Maccarinelli cannot wait to finally step into the ring with Johnny Nelson on 4 March in Manchester.
The Swansea cruiserweight, 25, who holds the WBU title, will finally get a chance to enter the big league when he faces WBO king Nelson at the MEN Arena.
"I've been waiting for this fight for a long time and I'm just so chuffed it's happening now," Maccarinelli said.
"I did worry it wouldn't happen, but as I've worked my way into the number one (challenger) spot I knew it had to."
Nelson has seen off 13 previous challengers for his WBO belt since stopping Carl Thompson to take the title in March 1999.
But the Sheffield fighter will be 39 by the time he faces his young challenger and Maccarinelli is eager to dethrone a man he has the greatest respect for.
"Johnny is an entertainer and I quite like the guy, but unfortunately for him he's got something I really, really want and on March the 4th I will be taking it off him," Maccarinelli added.
The cruiserweight showdown will be the chief support to an equally mouth-watering fight at super middleweight between Joe Calzaghe and Jeff Lacy.
Calzaghe will put his WBO title on the line against the American's IBF belt in a clash between two undefeated fighters.
Although Maccarinelli would have liked to have fought on home soil in Wales, he is happy to line up alongside compatriot Calzaghe.
"I would have loved the fight to have been in Wales but it didn't bother me where, when, what time as long as it was happening, to be honest," Maccarinelli said.
"I've studied tapes of Johnny for a long time and I've got a couple of game plans on how to beat him.
"I've said for a long time I can beat him, he's been telling people he can knock me out in three rounds - so on March the 4th we'll find out which one is talking from his behind!"
