As a kid, I was a huge fan of Boris Becker's volatility and Stefan Edberg, that was a time when I was actively playing tennis in school. Later, I liked Sampras for his serve and Agassi was an all-time favourite.

I still play tennis occasionally at the club, but somehow, in men's tennis, I couldn't bring myself to like Federer. I like Nadal as an athlete.

As you said, I believe greatness is very relative to the period one is great. Laver, Borg, Sampras were great then, Federer is now. I don't think it would be right to compare players across time or pitch them against each other. Our history is very great-event-oriented, if someone does something great, he becomes great. There is no superlative.
