Vitali Klitschko to take on Manuel Charr in last ever fight?

WBC heavyweight champion Vitali Klitschko will go head to head with Manuel Charr in Moscow in September in what could be his last ever fight.

The Ukrainian fighter will defend his world title later this year, which has thrown David Haye's hopes of going up against the 40-year-old into doubt with Klitschko expected to hang up his gloves for a career in politics.

The British boxer has previously been keen on taking on Klitschko after his miserable defeat to brother Wladimir but it appears that Haye could miss out.

Meanwhile, Haye, who announced his retirement last year, is preparing to face Dereck Chisora in the ring on July 14.
