Dame Kelly Holmes believes that Welsh hurdler Dai Greene can complete the set of major athletics titles by claiming gold at the London Olympic Games.

Sally Gunnell was the last British athlete to hold the set, and the two-time gold medal winner Holmes believes that the Team GB athletics captain can do the same by winning the big prize in London.

"I really believe that he can [win in London] and it would be again an amazing achievement," ESPN quotes Holmes as saying.

"If he can get the gold at the Olympics he then has the full lot of Commonwealth, European, world and Olympics and the only other person to do that was Sally Gunnell in the 400m hurdles."

Greene recently set his personal best in Paris.
