Jo-Wilfried Tsonga: 'I played unbelieveable'

Jo-Wilfried Tsonga has admitted that he was just too good for Rafael Nadal after his three-set win at the ATP World Tour Finals in London.

The Frenchman's victory has seen him progress through to the final four of the tournament at the O2.

"I just played so good," said Tsonga.

"It was difficult in the second set but I started well in the third and I just played unbelievable."

The semi-finals take place on Saturday.
