Zhang, Joshua a world apart

Olympic foes at opposite ends of fistic fortune

Zhang Zhilei and Anthony Joshua have charted decidedly different routes on the road to ring glory.

London's iconic Wembley Stadium will be the center of the boxing universe on Saturday night when 85,000 fans join multiple millions on pay-per-view in watching Britain's unbeaten Joshua (18-0, 18 KOs) try to defend his IBF world heavyweight title against former undisputed champion Wladimir Klitschko of Ukraine (64-4, 53 KOs).
