Klitschko sends warning to Joshua

Wladimir Klitschko has issued Anthony Joshua     

 with an ominous reminder of the 53 knockout wins

.Collected over his prestigious career     

Joshua, whose IBF heavyweight title will be up for grabs against Klitschko live on Sky Sports Box Office, offered "respect" to his veteran challenger's fighting style but insisted he preferred to watch risk-takers inside the ring.

Former unified world champion Klitschko said: "I think trainers and fighters have been studying my style and they are aware I can knock people out with both hands. I showed .it many times

"I do have a lot of weapons. One of them is the jab. It depends how much Anthony is going to give me to use,and which weapon I'm going to choos".
