Tyson Fury's manager shows the main reason Joshua lost to Ruiz

Anthony Joshua's loss to Andy Ruiz Jr at the weekend surprised the boxing sport.

Ruiz is now the new world champion in heavy weights after nominating the British, Joshua in the seventh round.

Although suspected of mechi, Tyson Fury's renowned promotor, Frank Warren has another version of Anthony's defeat.

He thinks Joshua has major defense problems, and he's noticed that since the 2014 mecca to Dillian Whyte. In addition, Warren feels that Joshua is trained by amateur trainers, who even had no idea what happened to Joshua at the drug against Ruiz.

The warning signs of what happened at Madison Square have been apparent some time. I've felt since the war with Dillian Whyte, that Joshua never improved his professional protection. He was left with amateur trainers, I was very surprised at the conversation they did between rounds. I am sure that Joshua will have an investigation and will answer many questions, the first will be his coach. He's continued to train with the GB team in Sheffield, from what I heard there's only 18x1...

Joshua has now lost all the titles, but he can be returned if the rhematci is formalised to Ruiz, which is likely to be held during November this year.
