WBC heavyweight champion Vitali Klitschko will face German Manuel Charr on September 1 in Kiev in what is set to be the last fight of his professional career.

Kilitschko (44-2) will be 41 by the time of the fight against the unbeaten 27-year-old and is expected to go full-time into politics in the Ukraine shortly afterwards, with parliamentary elections set for October 28.

A crowd of 70,000 is expected to watch Klitschko's farewell fight in the main football stadium in Ukraine.

The Syrian-born Charr is unbeaten with a 21-0 professional record.
