me the great, the unbeattable clay court player ever existed Thomas Muster
Well, this was for only about two years with not as good RG results as one would expect although he did lost to some great players like Courier in his prime, Guga coming up, Stich, Rafter(!?). I thought Muster didn't move nearly as well on court but could hit the ball flatter and harder. He also had a better serve. Nadal has become really good at a young age though so he should achieve more if he can stay away from some of the injuries that Muster went through. It's amazing how Muster developed his game for the hardcourts later on in his career with some really good wins at Key Biscayne, Dubai, semis at Indian Wells, finals at Cinncinnati, semis at the Australian.
Here are Muster's year end rankings by age (apologize for the format):
Years Old Rank
29 6 (reached #1 this year)
30 9 (did better on hard courts this year)
