I see that is your first post so you are new here... Well, then, welcome to the board
As for the answer, i hope Novak is going to remain persistent and will possibly win some more majors throughout his entire career and will thus put himself into the list of tennis legends. Don't know, really, cause competition for number one is very tough at the top. You have four exquisite players at this moment and for the beginning of the next season (Nadal,Federer,Djokovic and Murray), and the fact that competition on the top is so tough could simply be proven by the fact that no 2 and no 3 have more than 5000 points (Remember Marcelo Rios, at one point he had only something more than mere 3000 points yet he took the no 1 spot)... At one point, Novak managed to make the highest number of points for the third ranked player ever... That's the way it is today, so i know it is definitely not going to be that easy for Novak to gain no 1 position although he has definitely established himself in the tennis elite today.
That's my point of view... Hope i see you next time with more posts here in the offseason and in the next one that is just to begin...
