So I was just thinking about this match and I think it really was a critical match in the Federer Nadal rivalry. If Federer had won he would have had a mental boost, and actually believed he could beat Nadal on clay, which would have carried over to other surfaces, and probably would have resulted in him winning more of their future meetings. As it was Nadal won, and I think you can really see how it affected Federer, he never really put up a good fight against Nadal on clay after that, and it carried over to their matches on other surfaces. For example the AO final 2009, a match that Federer had on his raquet and lost. As for the match itself, having re-watched it I honestly don't feel that Federer deserved to win. He played, very, very well against Nadal for the entire match, however there were some crucial moments where he just didn't step up, and he let Nadal back into the match. I think that's further evidence of Nadal getting into Federer's head. For example the second set tie breaker which Federer was leading 4-2, and he shanked a forehand to make it 4-3. Then there were many moments in the fifth, like 4-2 40-30, the two match points obviously and 5-3 in the tiebreaker. Federer had a very good chance to win that point for 6-3 but he saw match point looming and he snatched at it. So he definitely had his chances to really put the match to bed, but he kept letting Nadal back in and getting tight. In my opinion if Federer had managed to win that match I think the head to head with Nadal would look totally different. Matches like FO 2006, 2007, Monte Carlo 2008, and Hamburg 2008, all matches I really feel (especially the last two), he lost due to choking effectively.
