Give me a fucking break. Posts like this from people like you is why people hate Nadal fans so much, always making excuses for injuries that no one really sees except them because it suits them to explain why he lost, 'cos, hey, a healthy Nadal never loses right?! He was running down rockets that Soderling was throwing at him that day but he lost. It happens. Cheer up, he still has 11 RG titles and, what's more, if his supposed chronic tendinitis was anywhere near as bad as a lot of the Nadal fans make out (it's not btw), then how the hell did he manage to win 17 slams lol?
We all know Federer lost that Wimbledon 2008 final and subsequent AO 2009 mentally due to him adopting a crap ineffective game plan at RG 2008 and playing crap and then the snow ball effect carried over from the poor RG loss. He also wasn't able to train properly first 6 months of 2008. Anyway, what exactly is your point, Federer beat him there too. So what? And, no, Nadal's knee has not been his worst opponent...he's won way too much already and there's absolutely no way you can say he'd have won anything else had he played a few more tournaments. He missed the last few events because they thought he might tear an ab muscle if he played, not because he actually tore anything. He skipped the AO 2013 cos of a sore tummy that apparently lasted 3 weeks. Wimbledon 2009 he chose to skip but he was moving fine at RG 2009. I can go on but I think you get the message, he actually chose to miss a lot of them and there was no real obligation to do so...
