Fres Oquendo (37-8, 24 KOs), 45-years-old and inactive since July f 2014, is still eager to fight in the heavyweight division.

Oquendo is still slated to challenge WBA "regular" heavyweight champion Manuel Charr on September 29th in Germany.

In his last fight, Oquendo lost a twelve round majority decision to Ruslan Chagaev (in a battle for the WBA 'regular' championship) - and Chagaev has since retired from the sport, and so has the majority of Oquendo's career opponents.

After losing to Chagaev, Oquendo took the WBA to court - and actually won a court order that forced the sanctioning body to grant him a world title shot.

"One of the most prestigious belts in the world. Once I'm crowned WBA world heavyweight champion they can never take that away - I'll be in the record books," Oquendo told Sky Sports.

The man who is recognized as the true WBA champion is Anthony Joshua, who holds the WBA's "super" title at the weight.

And Joshua is not a man who Oquendo would crown as one of the greats.

"Is he one of the greatest? No, he still has to prove himself. The calibre of opponents that he has fought are nowhere near the calibre from my era, the early 2000s," Oquendo said.

Oquendo has come up short in several world title attempts.

Now he must go through Charr, who won his last three fights - including a twelve round decision win over Alexander Ustinov in November of 2017.

"Who took more punishment?" Oquendo asks. "Me in my long career, or him in his average career? He has taken a beating way more than I have.

"The politics of boxing; I'm like the poster child. But I always had faith, and never lost hope. People ask me: 'how do you do it? Chechnya, Don King, the promoters, the managers - how do you stay sane?'"
