Novak Djokovic is in action in the first of the quarter-finals at the BNP Paribas Open in Indian Wells.
Djokovic may have gone off the boil during his fourth round clash but the draw's looking pretty good for him right now. After a spate of upsets, most of the serious challengers in his half are already out. Nicolas Almagro, John Isner and Gilles Simon may all be seasoned competitors but Djokovic will be thinking he could have faced far sterner tests at this stage of Masters 1000 event.
It's an especially good showing from Isner who's going for his second successive Masters semi-final. With his serve, he could make life uncomfortable for Djokovic if he gets past Simon.
In the other half, Roger Federer may be on a 13 match winning streak but the Swiss has looked a little shaky in the past two rounds, having to come from behind to beat Thomaz Bellucci and Milos Raonic. It doesn't bode well for a potential semi-final with his nemesis Rafa Nadal if he gets past Juan Martin Del Potro.
Nadal will almost certainly be waiting in the last four. With all due respect to David Nalbandian who's played superbly in beating Janko Tipsarevic and Jo-Wilfried Tsonga, the two-time champion has been the classiest man on show so far this week.
Expect to see the latest instalment of Federer-Nadal in the semi-finals. Federer has got into Del Potro's head this year, he's already beaten him three times this season.
