Oleksandr Usyk was given a stern test but the Ukrainian took a step towards a world heavyweight title shot in 2021 with a unanimous decision victory over a brave Dereck Chisora.

Usyk, the former undisputed cruiserweight champion, took some heavy shots from the British veteran, who weighed almost 40lbs heavier than his opponent in their headliner at Wembley's SSE Arena on Saturday night.

But Usyk used his superior speed and movement to assume control around the halfway stage, wobbling Chisora in the seventh round, and was given the nod by two scores of 115-113 and one of 117-112 on the judges' scorecards 

Usyk said afterwards: "It's a real test at heavyweight. Chisora is a big, hard guy. I fought his fight but I was expecting an even tougher fight."

Asked what mark out of 10 he would give himself, the southpaw responded: "Three."

But when asked whether he still wants to win a world heavyweight title, Usyk, the mandatory challenger for Anthony Joshua's WBO crown, responded: "Not just world champion. Undisputed world champion."

Chisora felt he deserved to be given the win as he claimed: "One hundred per cent. I was pushing the pace, I gave a couple of rounds away but I was pushing the pace.

"But the judges saw it a different way. I'm just disappointed with the result and I'm basically gutted."
