Former unified world heavyweight champion British Anthony Joshua showed his form ahead of the fight against the Swede Otto Wallina , which will take place on December 23 in the main event of the boxing evening in Riyadh, Saudi Arabia.

Let us remember that 34-year-old Joshua has already won two victories after two defeats in a row from Alexander Usik. In April, AJ won on points against Jermaine Franklin, and in August he knocked out Robert Helenius.
