#1. Federer. Record breaking slam champ. he will have trained hard in dubai base before landing. However with continual lack of match play it is doubtful whether he can regain his form quick enough. Others have belief now, but he is always certain of a relatively weak draw till the quarters or semis... #2. Del potro. 2nd favourite. If he can get to #4 rank by AO, he should avoid the top guys until Semis. Has belief in crunch situations backed up by the 2nd best serve on tour(right up there with soderling). #3. Djokovic- 3rd favourite. Form player of the tail end of 2009 with only two losses(davydenko and soderling). Has the belief and should be better prepared this time for the heat. Occasionally leaks unforced errors and GS form is patchy. #4. Murray - 4th favourite. Form very patchy backed up by personal off court break up issues. Still tough to beat on a hard court. #5 Nadal - 5th favourite. Is on the slide. Shots lack penetration. hopefully an intense off season fine tunes his shot making ability. #6 Davydenko - 6th fav. Definitely back to peak form. is a major worry for all the guys above. No one wants to draw this guy in their quarter. #7 Soderling - Definitely tough to beat with his serve. Others : Monfils, Tsonga, Verdasco, can impress from time to time Roddick not in contention IMHO as hasn't had any match play of any kind. Still injured.
