Ukraine's Wladimir Klitschko wants to become undisputed world heavyweight champion by claiming the WBC crown vacated by his older brother Vitali, according to reports.
According to the BBC, Briton Lennox Lewis was the last boxer to hold all the major belts in 2000, as the Klitschko brothers chose not to fight each other.
Klitschko said that is obviously his aim to bring the WBC title back into the Klitschko family, the report added.
This month, the older Klitschko swapped boxing for politics, the report said.
The 42-year-old is a Ukrainian opposition leader and plans to run for president in 2015, the report further said.
However, he was named 'champion emeritus', which would allow him to directly challenge a new champion if he wants to resume boxing, the report mentioned.
