Ronda Rousey’s devastating defeat at the hands of Amanda Nunes has continued to create shockwaves.

The UFC superstar was viewed as unbeatable, until former boxing champion Holly Holm knocked her out in the fall of 2015. Rousey took a year off and returned last month to challenge current UFC bantamweight champion Nunes - who blew away Rousey in 48 seconds.

Rousey dominant image in the MMA had led many to believe that she could do the same in boxing. The biggest supporter of Rousey's potential dominance in boxing was her trainer Edmond Tarverdyan.

Tarverdyan has been blamed by many, including Rousey's own mother, as being a negative force in her career. He made Rousey believe that she was a great boxer and a master striker, which led to her downfall against Nunes and Holm.

Former WBC champion Diana Prazak was often used as a sparring partner for Rousey.

"She was stiff, she's not a striker, and you don't punch a puncher," Prazak said about Rousey's latest defeat exclusively to Sky Sports.

"She's not a boxer, that's not something you pick up in a couple of months. I started working with Ronda over two years ago but, but when she was going to fight Holly Holm, they stopped me being her sparring partner. Our spars were always battles, they were harder than the fights she was having. We had great sparring - she was getting better. My opinion? It wouldn't have been good for her confidence to keep sparring me, and not being successful. Edmond made that decision. She isn't a striker."

Tarverdyan has told reporters over and over that Rousey was such a good striker that she was dropping boxing world champions for the count with body shots in sparring.

Prazak, who says Tarverdyan was talking about her, called him a liar - and she also hopes Rousey comes back with an entirely new team.

"He was talking about me," Prazak said. "My trainer rang him to say 'why would you make that up?' It's an untruth. I hope she comes back with a totally different team around her who look after her safety."
