I really hope you're right, but...
1: He's lost twice to Federer when it really mattered, Grand Slam finals.
2: He failed to take his chances yesterday, don't think luck was really an issue.
3: Federer looked like the younger man yesterday, never showing any signs of fatigue or emotion. Murray looked tired, distressed and very sore at the end.
There is a lot still to come from Federer.
I'm a patriotic Scot and I want him to do well, but there are lots of good players in his way - and it will take an exceptional effort to overcome the psychological battle next time he finds himself on court with Federer.
