David Ferrer has said that he is ready to fight in his ATP World Tour semi-final against Roger Federer today.
The Spaniard, who has never beaten the world number four, lost his first match of the London tournament against Tomas Berdych on Friday night.
"I will try to fight a lot," the world number five said after the match. "I've never beaten Roger, and I hope tomorrow I can change that."
Federer has won all three of his matches so far at the event.
