Wladimir Klitschko believes Anthony Joshua will become the new "dominant force in the heavyweight division".
The Ukrainian, now 39, currently holds three of the four major belts but has no doubt that the British Olympic gold medallist will win a world title sooner rather than later.
In an interview with Ringside, Klitschko has no doubt that Joshua is 'that' good and will rule the sport's blue riband division.
"I can talk about Anthony Joshua a lot," he said.
"I can say a lot of good things about him and I like the way this guy is developing so well.
"I would say - probably on a short line - I am so confident he will become the dominant force in the heavyweight division.
"I would put any money on Anthony Joshua winning any other fight that comes up. That means a lot!"
Joshua spent time in Klitschko's training camp last year and has since moved to 13-0 with 13 knockouts inside three rounds.
The last one of those stoppages was an explosive two-round demolition of the experienced Kevin Johnson, who took Vitali Klitschko the distance back in 2009.
And Wladimir again, pulled no punches when it came to praising Joshua.
"I was expecting Anthony to win this fight but I never thought he was going to win that comprehensively!"
