I've seen alot of Federer fans and tennis fans in general on twitter claiming that that Fogninis withdrawls makes Djokovics French Open tournament a hell of a lot easier. I happen to disagree, and if you're a Federer fan like me, then you should be quite pleased!
Fogninis withdrawal, although I'd describe it as pretty wimpish, and not something a Federer or Nadal would do, is good news. It now means Djokovic has a whole 4 days off before his next match, which in all likelihood will be against Roger Federer. 4 days is a huge amount of time, and trying to stay focused for that amount of time could be pretty difficult. Novak has been playing awesome tennis since January, his confidence is sky high so I'm sure he relishes matches and they can't come round quick enough.
So far apart from 1 set against Del Potro, Djokovic hasn't been tested in the slighest, and although he's played solid, he hasn't had to do anything out of the norm. Fognini would have been another easy match (likely straight sets, 6-1 in the third no doubt). Alot can happen in 4 days – hopefully Novak loses some of his sharpness and then runs into a red hot Federer in the semis who ends the winning streak and goes on to whoop Nadal in the final.
