I don't remember seeing this thread hovering around here, so I decided to open it up and see what great memories you have to share.
The best I've seen Gonzo play was against JCF in Basel 02. The first two sets were OK, but the third... Gonzo was unplayable! Just so good! I actually remember him hitting a HUGE forehand return that landed right next to Ferrero, but he just couldn't do a thing, it was so fast.
For Taylor it's that annoying US Open match against Agassi, when he was hammering Andre but was forced to retire. Both matches these two guys played against each other (USO 03 and that 16-14 final set in the Bronze Medal match in Athens) were great too, especially that USO encounter, it was fantastic!
For Alex... Well, I don't actually remember a match in which he was actually brilliant all through-out
I guess it was one of his FO victories. I remember that LOOOONG encounter with Pavel. That was one hell of a clay-court match.
For Fed, it's just too damn hard to say. He played just BRILLIANTLY in Doha this season, simply the best I've ever seen him play. I saw all of his matches from there this season, and I guess the best was against Ljubicic in the final. Ivan just coulnd't get his enormous shots past him.
