Golden Boy Promotions CEO Oscar De La Hoya is not impressed in the aftermath of Anthony Joshua's big win.

This past Saturday night, Joshua added the WBO belt to the WBA, WBF and IBO titles he already held, by going the distance with Joseph Parker and winning a unanimous points decision in Cardiff.

The London 2012 super-heavyweight Olympic champion came into the contest with 20 wins, all via knockout, in his 20 professional fights to date. He added a one to that tally with two judges awarding him the fight 118-110 and the other 119-109.

And now, Joshua knows exactly what his next aim is – Deontay Wilder and his WBC belt.

De La Hoya took to social media - telling both Joshua nd Wilder to call him if they wanted to become superstars in the United States.

It's not the first time where De La Hoya made a play to promote the two undefeated heavyweights.

De La Hoya's company prompted Wilder for a better part of his career. They parted ways after January of 2015, following Wilder's decision win over Bermane Stiverne to capture the WBC heavyweight title.

"If Anthony Joshua and Deontay Wilder want to become household names in the US of A and stop doing mediocre ratings on Showtime, call me and I’ll make you superstars in the beautiful USA," De La Hoya wrote.

“To be honest, the Anthony Joshua fight did 400k homes on cable and Wilder has done over 1.2 million. I’m saying he’s not making huge money! He’s a champion, I respect it. But he’s no Mike Tyson, that’s for sure.

“I’m a fighter who loves boxing and breathes boxing all my life, I want Anthony Joshua to be considered a legend one day and make the most money doing it!

“If I was promoting Wilder I would take him to the UK and fight him with Joshua then have a rematch in the US. I made [Wilder] champ and look at him now ever since he left.”
