Yeah but (a) Nalbandian lost the first two sets in tiebreaks, whereas Federer won the first two sets comfortably (with two breaks more than Gilles in each set) and (b) it wasn't in a major.
True. Plus Fed had some ready-made excuses for that match, sth like he came back from some injury and haven't play for a little while eventhough he still comfortably beat everyone else to the final to meet Nalby. While Nalby got called from off-season vacation to ditch his fishing trip to show up as an alternate and almost has to play with his fishing gear and still beat everyone and Fed
But seriously, I'm impressed that after 2 sets of beatdown and Gilles didn't get down on himself and then he brought out his good form. I really think his fight is definitely one of the best out there.
