Let me put in a specific prediction. Novak will not win all the three RR matches.
In particular, I think Cilic might win against Novak, if he does not have injury issues,
with the new found confidence.
This is not a wishful thinking prediction. If you have seen recent matches
between Cilic and Novak, you might have noticed that Cilic is closing the gap on Novak,
so to speak. In RG they went to four sets and in Wimby, it they went to 5 sets (although
Cilic lost the last two meekly).
More than these two matches, the one that really impressed me was Cilic's first
set against Novak in IW this year. Cilic was in a zone and hitting the lines with
powerful shots. But, then he could not sustain it, partly due to his lack of self belief.
Now, that he is a GS champion when in that kind of situation he might bring more heat
on instead of folding.
