James Ali Bashir, an assistant trainer to former division ruler Wladimir Klitschko, believes everyone will be shocked by his boxer's performance in the upcoming fight on April 29th against IBF world heavyweight champion Anthony Joshua (18-0, 18 KOs).

"Wladimir Klitschko will be very well prepared when he comes into the ring. He's always coming to fight at 100 percent readiness. Anthony Joshua is a large, young, strong, active fighter with a very strong punch. Joshua will be a very serious fight. In the ring, you are going to have two large, well-trained punchers. Someone will be knocked out," Bashir told BaylorIC TV.

Klitschko, 40 years old, has been out of the ring since losing a twelve round decision to Tyson Fury back in November 2015. The outcome was viewed by many as the 'upset of the year.'

Several attempts to stage a rematch with Fury feel through. And eventually Fury vacated his WBA, IBO, WBO titles to focus on his failing mental health.

The vacant WBA, IBO titles will also be at stake in the Klitschko vs. Joshua showdown.

Because of the loss, the age factor and inactivity, Joshua is being pushed as the favorite in the fight - and many experts predict he will end Klitschko's career with a knockout.

"We do not know how strong Joshua's chin is. But Wladimir does not a weak chin, as some say. Sam Peter put him down three times, and each time Wladimir got up and won the fight. And Peter - this is one of the most powerful punchers in the heavyweight division in the last 15-20 years," Bashir said 

"Wladimir Klitschko is going to shock everyone. I expect an incredible fight. I don't think it will be long, but it will definitely be an explosive fight. One of these guys will get knocked out. There is no chance that this fight will go the full distance."
