Fed-express slowing down

Two weeks ago, Novak Djokovic captured his second grand slam trophy of his career.  Both of his grand slam titles happened in Melbourne soil, and both were semi-final victories againsts Roger Federer.  And for the second time since 2003, Federer is again endangered of falling down into the number three spot of the world rankings with just a mere 85 ranking points.

With the string of grand slam defeats piling up one after the other, it is difficult to deny that Federer is indeed on a decline.  We heard and read these on papers before but Roger was able to bounce back proving his critics wrong by taking back his number one sport and winning a couple of grand slam titles.  But I guess the question now his it's becoming more frequent for Federer to be in this discussion nowadays which is definitely a factor for signs of decline.

Can Roger Federer still get back to the top of the rankings?  It would be a herculean task to achieve considering clay court season is underway for the next few months.
