Murray clarifies corruption comments

The Scot voiced his opinion on the subject of match-fixing, saying: "It's pretty disappointing for all the players but everyone knows it goes on."

However, his comments have drawn criticism from a number of fellow professionals, and Murray told his personal website: "When I said, 'everyone knows that it's going on', I meant that everyone has probably heard that three or four players have spoken out about being offered money to lose matches - which they refused."

He added: "I am glad that the tennis governing bodies are coming together to set up an anti-corruption unit to address this and I stand fully behind this effort.

"Tennis has been a part of my entire life and it is a privilege to compete at the highest levels of the sport."

World number two Rafael Nadal had earlier questioned whether Murray really had any great knowledge of corruption.

"I doubt Murray knows more than anyone else - he's gone overboard and there are no fixed games," he said.

Russian Nikolay Davydenko, who is at the centre of an ATP Tour investigation into a match two months ago involving himself and Argentinian player Martin Vassallo Arguello where suspicious betting patterns emerged, was also dismissive of Murray's earlier comments.

"It was folly of him to say this," he said.
