Well I think he'll dodge Rafa in the clay season, he'll lose before the final of each clay event to make sure Rafa doesn't gain any confidence in the rivalry.
So whatever he wins will have to be after June :armed:
I mean, trolling effort (3/10) aside, Djokovic has 1 ATP title so far - whether or not the ATP runs the tournaments directly they make no distinction between slams and the other tournaments in terms of being ATP titles, and still list them as titles won by the player on their own site:
Records and stats for the ATP Tour elsewhere also never make a distinction (quick question - how many ATP titles does Federer have? Without specifically stating you mean something different, the answer you will get is 101).
Personally I predict Djokovic will win 2-3 slams and a couple of other titles to end up with 4 or 5 for the year.
