"I can't really speak for Joshua because everything that happened in training camp played an important role in his performance in the ring. So I can't speak on his behalf about what went wrong and right in training camp. But based on what I saw, he made some fundamental mistakes. Joshua kept his hands low. When he was delivering punches, he was leaning forward and opening himself up for counterattacks.
I don't know what happened, but I saw him make some mistakes. He didn't have these mistakes before, so I don't know why Joshua made them," said Zhilei in an interview with YouTube channel Boxing News.
Recall that on September 21, Dubois knocked out Joshua in the fifth round in the main event of the evening of boxing at London's Wembley Stadium.
