Ryan Aston is a winner on Haye bill

Ice-cool Ryan Aston cheered up British fight fans at the biggest boxing show of the year in Hamburg.

The Dudley middleweight continued a punch perfect start to his professional career on Saturday night with a four-round points win over Bulgarian tough guy Zuhari Muatfchiev, coming just seven days after victory on his paid debut.

Aston's win was the opening fight of the show - topped by David Haye's heavyweight unification battle with Wladimir Klitschko - and the Imtech Arena was slowly filling with fans when the Black Country prospect ducked between the ropes.

The 20-year-old former amateur star then took his place at ringside to watch Klitschko outpoint Haye, adding his opponent's WBA title to his WBO, IBF and IBO belts.

Haye intends retiring when he turns 31 in October and, with a match against WBC champion Vitali Klitschko looking unlikely, he faces an uncertain future.

But Aston, part of the Haymaker promotional stable, has much to look forward to.
