There were some classic shots, but it was a baseline slugfest for most of the time. Service ruled with very few breaks. It became counted as a "classic" simply because Federer came back from 2 sets down to take it to the fifth. That too on very few well-played points in the tie breakers.
Some of the best: 2001 - Ivanisevic, wildcard, thrice runner up, fighting tears while serving out the match, finally overcoming Patrick Rafter in 5 sets 6–3, 3–6, 6–3, 2–6, 9–7 1990 - Edberg bt Becker, classic serve and volley match 6–2, 6–2, 3–6, 3–6, 6–4 1980 - Borg bt mcenroe, classic old v new match, the old holding on for his 5th straight till mcenroe bt him next year 1-6 7-5 6-3 6-7(16) 8-6
