Vitali Klitschko unanimously out-pointed Dereck Chisora for a 10th successive defence of his World Boxing Council (WBC) heavyweight title in a stormy clash at the Olympic hall here on Saturday.
After being slapped by Briton Chisora at Friday's weigh-in, Ukrainian Klitschko got revenge over his provocative challenger but he spent a lot of the fight on the back foot before earning scores of 118-110, 118-110, 119-111 from the judges.
Despite the wide margin of the scores, Klitschko was made to work for every moment of the 12 rounds in a plucky effort from Chisora. Germany-based Klitschko improved his record to 44 wins, and two losses with his 41st stoppage while Chisora suffered his third defeat in his 18th fight.
