Oh no, here we go again. Nadal doesn't count, Federer made the mistakes, Federer has the keys to overcome him.
Next time he'll overcome him guys, no doubt about it. So be calm, wait till the next match and we will be in this same situation again.
You're terribly underrating Nadal. Period. You think he's just like a sparring who Federer is training with. I'm going to reveal something that probably is going to hurt you, I'm sorry but sometime someone needs to tell you this: Nadal actually is learning something of tennis throughout his career. He learnt something when he was beaten in their first match in the Miami final. He learnt something past year (his first year at the elite), he's just recently turned 20, he has the mentality to improve his game all the time... so when are you going to accept Nadal is not a sparrying? He's a player who learns a lot. You're biased.
