Which R is it? Roger or Rafa?

I realized that tennis fans/critics really have very bad memory.  They flip flop just as quickly as you change your mind of what to wear for the day.

2 years ago when Roger lost hist No.1 ranking and Wimbledon trophy to Rafa, people started talking about Roger's fading game.  They say this is the passing of the crown, Roger should retire, he's already passed his prime, blah blah.....

Then came 2009 where Rafa went down with tendinitis on both of his knees which opened up the opportunity for Roger to take his first French Open title, his 15th Grand slam title in London, and get back to No.1.  Roger even won the AO in 2010 which firmly stabilizes him as the GOAT in tennis history.

Things can quickly change in tennis, same as how a single point can turn around the whole match.  With Rafa winning the next 3 slams after AO, Rafa has gone up into the debate of tennis GOAT which many people believe he can even surpass all what the mighty Roger have achieved.

	Roger Federer	Rafael Nadal
Head to Head	7	14
Age winning first GS	22	19
Age winning career GS	28	24
No. of GS	16	9
ATP Masters Title	15	18

I think let us all seat back and watch how these 2 will fair for the next 3 or 4 years as Roger plans to play on until at least the London Olympics in 2012.  When both of them hang up their sneakers, that would be the perfect time to debate who really is the GOAT. (The info above is only accurate as of this writing.)
