Promoter Frank Warren is hoping to secure WBO light-heavyweight champion Nathan Cleverly a title unification clash with boxing legend Bernard Hopkins.

Cleverly stopped Pole Aleksy Kuziemski in four rounds last weekend in a successful first defence of the WBO crown he inherited following Juergen Braehmer's last-minute withdrawal.

Hopkins made history after outpointing Jean Pascal to claim the WBC and IBO titles in Canada on Saturday night at the sprightly age of 46.

Warren now wants the American, who has racked up 55 victories from 60 fights, since making a losing debut over two decades ago, to face Cleverly in Wales.

Unbeaten Cleverly, who was born the year after Hopkins turned pro, called out the veteran following Saturday's win at the O2, insisting he wanted 'big fights'.

"It would be nice to get it on some time before Christmas," Warren told the BBC, adding that Cardiff's Millennium Stadium would be the ideal venue for the showdown.

"If we could make Cleverly and Bernard Hopkins, that's the home for it.

"Anything's likely at the moment. Nathan is up there with all these guys. He's a fabulous champion and I do believe he's got the beating of most of them."

Meanwhile, Cleverly has told Enzo Maccarinelli to get in line after his former stablemate called for an all-Welsh showdown.

Former WBO cruiserweight champion Maccarinelli was ringside at the O2 on Saturday night to witness his compatriot's four-round stoppage of Kuziemski.

Maccarinelli, who is dropping down to light heavyweight in a bid to relaunch his career, wasted little time in throwing his hat in the ring to face the newly-crowned WBO champion.

"I've heard he wants a crack but he'll have to join the queue," Cleverly told the South Wales Argus. "He's got nothing to offer me at the moment.

"He's got five defeats on his record and he needs me a lot more than I need him. He needs to start from the bottom and prove himself again if he wants to take me on."
