Vitali and Wladimir Klitschko are the stars of heavyweight boxing
Newly re-crowned WBC heavyweight champion Vitali Klitschko has set his sights on Russian Nikolai Valuev's WBA belt after his win over Samuel Peter.
Klitschko's younger sibling Wladimir, is the WBO and IBF champion and the Ukrainians are the first brothers to hold heavyweight belts simultaneously.
Now only Valuev stands between the brothers and all four world titles.
"It would be really great if all four titles were in the family's hands," said Vitali.
Vitali became world champion for the third time in Berlin on Saturday when Peter, from Nigeria, failed to come out of his corner for the ninth round.
"Brother, we have done it, we have achieved our dream!" said younger sibling Wladimir after the victory
Vitali added: "We made our dream a reality. I am unbelievably happy. I am in top form and I see no obstacles to boxing on as a world champion."
He must defend his WBC title within 90 days against Cuba's Juan Carlo Gomez, but future opponents after that are unclear.
Vitali claimed his first world title against Herbie Hide in 1999 when he won the WBO title which he then lost to Chris Byrd in 2000.
He fought for the WBC crown in 2003 but lost to Britain's Lennox Lewis before hitting back to clinch the title against Corrie Sanders in 2004.
Klitschko defended the belt in December of the same year but was forced to retire with a knee injury before returning in spectacular style on Saturday.
Russia's Valuev has already said he would be prepared to meet Vitali in the ring but he is looking at a voluntary defence of his title in December with Evander Holyfield being linked as a possible opponent.
"That would be a difficult, but interesting fight (against Klitschko)," he said.
