After weeks of speculation, Anthony Joshua's next fight has finally been announced.

Having beaten Joseph Parker in March, 'AJ' has been lining up his next major fight. 

Even though we're all eagerly awaiting for his clash with Deontay Wilder to be confirmed, Joshua also knew he was obliged to fight mandatory challenger Alexander Povetkin.

Joshua's WBA, IBF and WBO belts will be on the line when he faces the Russian at Wembley on September 22.

And though Joshua's focus could well be shifting towards a mega showdown with American Wilder, another British boxer has warned him that his first opponent is a dangerous one.

David Price knows all about Povetkin's threat having faced him in the ring in Cardiff in March.

Povetkin floored the Liverpudlian in the fifth round and Price has understandably warned Joshua he faces a stern test.

"He's only lost to Klitschko. He might not look much on the face of it as in size, and physique and everything else, but I can tell you from first-hand experience that he's a very accurate puncher.

"He's not easy to land the right hand on, which is what I was looking for. If you watch him against Wladimir Klitschko, Klitschko very rarely landed his big right hand, it was left hooks.

"There is always a chance of an upset in boxing, but it isn't as one-sided a fight as some people are seeing it. They should be excited about that fight, because it will be good while it lasts."

Price has advised AJ to drag out the fight as long as possible, and his chances will increase as a result.

"The longer it goes on the more it's in Joshua's favour, because if Povetkin fights like he did against me, he was loading up.

"He may not fight like that against Joshua. He was loading up, because he thought he could just knock me out as soon as he hit me, but after four rounds, he was starting to blow, and in a lot of his fights he does start blowing after four rounds.

"Let's look at Povetkin's knockout victories against fighters who have been stopped before, like Takam, Duhaupas, Manuel Charr. Fighters like that, Povetkin has iced them. He's knocked them out cold."

When asked how he thinks the fight will unfold, Price still sees an AJ victory, but thinks it will be a hard-fought one.

"If Joshua takes that into account, he will go into the fight cautious early on, and then as the rounds go on, you'll see Povetkin - he'll be 39 by the fight - start tiring and Joshua will jump all over him. I think he'll win by stoppage."

Only time will tell if Price is right, but Joshua has certainly been warned.

Wilder may be the opponent that everyone wants to see him against, but it seems that he'd be wise to take the threat of Povetkin very seriously.
