ROMULO Koasicha has warned St Joseph's star Lee Selby he’ll end his winning streak when the pair meet in a WBC world featherweight title eliminator at the Motorpoint Arena in Cardiff on Saturday.

Mexican Koasicha juggles his studies for a degree in mechanical engineering with his blossoming career in the ring and is aiming to land the vacant WBC international belt and catapult his name into the world title mix in the process.

“I’m very happy and motivated as it’s a very important fight,” said Koasicha. “I’m excited to fight in Great Britain and out of Mexico for the first time. We’re going there to win.

“We’ve seen a few videos of Selby. He’s a good boxer with a lot of technique; he knows how to manage distance and punches hard for the featherweight division. But we have the strategy to fight and win.

“I only had a two week break between my last fight and starting preparation for this one. I have seen in his videos that he lets his guard down and all this forms part of the strategy. If he tries something different then we’ll adapt. Depending on how he fights we’ll adapt but above all we’re going to control the rhythm of the fight.”

Koasicha will not have seen a boxer with the style and awkwardness of Selby. Does he foresee problems adapting, in particular to the Barry boxer’s ability to throw quick shots from difficult angles?

“I’m a versatile boxer,” said Koasicha. “There are a lot of styles out there, when I fight, I see how my opponent is fighting and I adapt my style to that. If I need to attack then I do that, or if I need to be more technical I can do that.”

Koasicha’s clash with Selby is part of a huge night of action in Cardiff as Cefn Fforest ace Nathan Cleverly steps up to cruiserweight for the first time against Guyana’s Shaun Corbin with the WBA intercontinental title on the line.

Newbridge's Gavin Rees bows out from the professional game with a rematch against St Joes tough guy Gary Buckland, Liverpool’s super middleweight star Callum Smith defends his WBC international super-middleweight title against Swansea’s Tobias Webb, Dale Evans faces Mark Douglas, plus there’s action for Chris Jenkins, Mitch Buckland, Robbie Turley and Alex Hughes.
