I played great - Federer

Roger Federer says his dominant 6-3 6-0 win over Rafael Nadal was "a great match from start to finish" after the Swiss produced some stunning tennis to defeat his great rival and advance to the last four of the ATP World Tour Finals in London.

Federer reveals the key to his success was hitting powerful, purposeful shots into the corners of the court against the Spaniard, and avoiding giving Nadal "nothing balls" that would allow him to dominate the rally.
