'I've fought both Joshua and Takam'

Michael fought Anthony Joshua in 2014

As Anthony Joshua and Carlos Takam prepare for their boxing heavyweight title match in Cardiff - one man knows more than most about what they can expect.

Michael Sprott is the only man in Britain to have fought both of them.

The 42-year-old first lost to Anthony in November 2014, before going down in five rounds to Carlos seven months later.

And his money is on AJ taking Saturday's match by round six.

Michael Sprott says Carlos Takam has a "head like granite"

Newsbeat went to visit Michael at his home in Reading to get some fighting talk.

He's warned Anthony not to take the Frenchman lightly.

"Takam is like a bodybuilder, very strong, and like Anthony says he's got a head like granite. He can definitely take a shot."

Michael Sprott was Anthony Joshua's 10th professional opponent

Michael's fight with Anthony Joshua ended in a first round knockout, but he feels it was cut short.

"I was more disappointed the referee stopped the fight so quick," he tells Newsbeat.

"I'm not saying I would have won. He did what he did. He's a great athlete and from that fight alone I said 'This kid's going the whole way'."

For the former British heavyweight champion, the key to a Joshua victory is an early knockout.

He says: "If I was his trainer I would tell him to get rid of Takam as quickly as possible, maybe as early as the first couple of rounds.

"The longer the fight goes on the more dangerous it is for Anthony Joshua."

Joshua only found out he was fighting Takam less than two weeks ago. The original fighter, Kubrat Pulev, pulled out injured.

Michael says he's not ready to hang up his boxing gloves just yet

Michael thinks the late change could prove problematic for the 2012 Olympic gold medallist.

"Before, he was fighting someone who was 6ft 4ins (1.95m). Now he's fighting someone who is 6ft 1ins (1.85m).

"Takam has very long arms for his size and he is quite elusive," he says.

"And remember - when Lennox Lewis fought Vitali Klitschko - he was meant to be fighting someone else, and Lennox should probably have lost that fight."

Michael, who says he's not ready to hang up his gloves just yet, believes it will be an entertaining fight.

"Joshua is going to come at him, and Takam will try and counter. Guns for guns I think.

"I've got Joshua stopping him within five or six rounds."
