Olympic champion Rafael Nadal is desperate to rid himself of an embarrassing blemish at the London Games -- the record for the shortest appearance.

The world number two Spaniard, fresh from a record seventh French Open and aiming for a third Wimbledon title next week, admitted that although he enjoyed his Beijing experience in 2008, the 2004 Games were a different matter entirely.

"I have one record in Athens that I am the sportsman who spent less time in one Olympic Games, because the week before I played in Sopot. I won my first tournament. I arrived that Saturday night, I lost on Sunday, and I went home," he said.
