Djokovic ready for Federer challenge

Novak Djokovic is looking forward to facing Roger Federer after beating Jo-Wilfried Tsonga in the French Open quarter-finals.

The world number one looked like he might crash out of the tournament after going two sets to one down against the giant Frenchman and struggling in the fourth.
But, after saving four match points, the Serbian ace rallied to force a decider, which he ran away with to book a last-four clash with the Swiss star in a repeat of last year's semi-final at Roland Garros.
Djokovic was still unbeaten at that stage of the 2011 season but lost out in four sets as the 16-time Grand Slam winner raised his game a notch or two to move into the final.
Federer was also in trouble on Sunday and had to fight back from two sets down to overcome Juan Martin del Potro 3-6 6-7 6-2 6-0 6-3 and it looks set to be cracking contest between the talented duo.
Djokovic has never won the French Open and admits he is expecting a severe examination from Federer in Friday's semi-final.
"The good thing is that we both have two days off to rest," he said. "You can always expect Federer to play his best at this stage of a tournament and I hope to have another great match like we had in 2011. It's always a big challenge to play Roger."
