If he doesn't do something soon, he'll probably never reach world #1.
That is what I am seeing too. Del Potro and Murray are improving and moving up fast while Djokovic is struggling to try and sustain for periods of time his level from spring 2007-spring 2008 at best. Unless something changes fast he will be well behind both before too long.
Also people keep saying when Federer and Nadal are gone, well there is a good chance Federer and Nadal wont be done winning majors until 2012 or so, and by that time there will could be who knows players emerge as top threats in addition.
You also need consistency to reach World #1. Djokovic showed consistency in 2007 and the first half of 2008 but has lost that consistency since.
