Vitali Klitschko is eyeing a return to boxing and a showdown with Anthony Joshua.
The Brit famously stopped Wladimir Klitschko in Apri l, forcing the Ukrainian to retire.
But now Vitali wants to avenge his brother's defeat and believes he would get the better of the unbeaten Joshua.
The 46-year-old hasn't fought since 2012 and has since turned his focus to politics.
But he told FightHubTV: "I miss boxing very much. Boxing will always stay in my heart my whole life.
“A fight against Joshua is my best wish. I have a feeling I can do it better, I have to fight Joshua and bring back the belt to the family.
"Wladimir was for a long time the best heavyweight in the world. Joshua stopped him and this means he is the best one.
"But that was just a lucky fight, a lucky day for Joshua."
Joshua recovered from being knocked down in the sixth round to beat Klitschko in front of 90,000 fans at Wembley.
But Vitali feels responsible after taking his brother to take it easy despite flooring Joshua for the first time in his career.
“I expect a big-muscled athlete to not recover, I was surprised, Joshua recovered so fast and stopped Wladimir," he added.
“If I didn't tell him to stop, then Wladimir might have knocked him out, six or maybe round number seven."
