Vitali quiet after Haye questions Charr win
Klitschko stopped Charr in the fourth round of their Moscow encounter, successfully defending his WBC heavyweight belt for a ninth time. The end came when the doctor advised the referee to stop the bout due to a cut above the challenger's right eye.
Charr claimed the doctor - not Klitschko - had won the fight and he called for a rematch, which the champion politely declined. Haye has made no secret of his own desire to fight Klitschko, and he sided with Charr on Twitter.
"I feel for Charr," Haye tweeted. "If roles were reversed, do you think K2's regular German doctor would have stopped Vitali Klitschko?"
Haye was recently welcomed back into the WBC after talks with president Jose Sulaiman, so there appears no obstacle to a heavyweight showdown either at the back end of 2012 or in February 2013.
However, at 41 years of age Klitschko continues to carve out a career in politics, heading an opposition party called United Democratic Action for Reform (UDAR) in Ukraine. And he insists that now becomes his main focus ahead of deciding on another fight.
"I'm facing major tasks and not only in sports," Klitschko said. "I'll fly to Kiev in the morning and will be fully occupied with preparations for the parliamentary elections [in October] as the leader of the party.
"I'm 41 and I'm still boxing, but one cannot trick nature - I will have to hang my gloves on a nail soon."
