World heavyweight champion Anthony Joshua has shared a message for Deontay Wilder ahead of their potential summer fight.

The 28-year-old Londoner - who recently beat Joseph Parker unanimously on points - only needs Wilder’s WBC heavyweight crown to become undisputed king of the division.

Wladimir Klitschko is the only man to ever drop Joshua in the ring and the 42-year-old Ukrainian believes the American could be a difficult opponent.

“It would be a dangerous fight for Anthony Joshua,” Klitschko told the Sunday Times. “I’m not saying he wouldn’t win it but Wilder has something.

“Due to his weight, he is extremely fast. He has good power in his hands and he’s extremely fast.

“Maybe he’s kind of wild in his technique but those punches are coming from who knows where.

“He is hard to defend against — where is that punch going to land or which side is it coming from?”

AJ's chilling message for Wilder

Joshua currently holds the WBA, IBF, IBO and WBO belts, whilst Wilder has held the WBC belt since 2015.

They are reportedly close to agreeing a summer fight in a UK stadium - and the 32-year-old American has been given a stern warning.

“He’ll do a great job of promoting and selling himself and I’ll do a great job of knocking him out,” said Joshua, as per independent.ie.

“People talk a good game, but it’s about backing it up in the ring. People like to trash talk, but I do it in a more fun way unless it gets personal and then I’ll give as good as I get.

"I like to beat them in the ring. I’ve never heard of a record for winning press conferences or stare downs.”

Fighting talk.

Boxing promoter Eddie Hearn told fans that Team Joshua are doing everything they can to fight Wilder next.

"I believe it will happen in the next one or two fights and, trust me, we'll be doing everything we can to make it happen in the next fight," Hearn said last week.

"It is really down to Wilder. Of course, there are negotiations to be done but again, if you believe you can win, it's not as if we are offering you peanuts – it's five times your biggest payday."

If Hearn is able to get these two in the ring, it would be the biggest fight of 2018.
