Former world champion Joshua Clottey is not rushing for a big fight.The Ghanaian boxer says he has learnt major technical lessons after an all-attack display earned him a second knockout win against American Calvin Green at the weekend in a light middleweight contest staged in Texas.This is Joshua’s first bout since losing to Manny Pacquiao 20 months ago.The Ghanaian boxer who previously held the IBF welterweight title is now looking forward to dominating in the Light Middleweight division after improving his record to 36 wins 4 draws and four losses.Joshua Clottey told Joy Sports that, he will welcome any challenge but will rush for a big bout.“I’m not rushing for something big but if the opportunity comes I will take it,” said Clottey.
