World number two Rafael Nadal has conceded that there is little he could have done to defeat Roger Federer at the ATP World Tour Finals yesterday evening.
Federer achieved a straight-sets victory over the Spaniard in just one hour at London's O2 Arena.
After the match, the 25-year-old revealed that his opponent "played too good" for him.
"The score is true, and today he played too good for me," said Nadal. "Just accept that today when you play against Federer and he's playing like this, the only way to stay in the match is have free points with the serve.
"For the rest his level was too high in this surface. I didn't had these free points as usual."
Nadal must now beat Jo-Wilfried Tsonga tomorrow to qualify for the semi-finals.
