Boxing: Vitali Klitschko could be tempted by final pay-day against David Haye after no-contest

It was Vitali Klitschko's easiest world title fight and he looked embarrassed when Manuel Charr was stopped on his feet but out of his class in round four on Saturday night in Moscow.

Charr, who was born in Lebanon, was never in the fight and was cut over the right eye, ruled out by the ringside doctor and then he put on a dramatic display of protest inside the packed ring before calming down. He had been dropped in round two, landed just a few punches and was being painfully softened up for a long beating before the doctor's merciful intervention.

Klitschko retained his WBC heavyweight title for the ninth time since returning from his four-year forced sabbatical, an absence made necessary by injuries, and must now, at 41 and after 47 fights, make a decision on his future. On Saturday night he looked bored and old and he has made it clear that politics in Ukraine is what really motivates him.

However, there is always the chance of one last fight, and it would be a lucrative final appearance, against David Haye, who lost to Vitali's younger brother, Wladimir, last year but remains a big attraction in Germany. "The fight could happen but I'm not convinced that Vitali wants to meet me – he is not stupid," said Haye. The pair have been swapping insults since 2009 and a fight has been close on several occasions.
