I think it's amazing that Murray managed to get to the finals of another GS. It's not every day that this happens for Murray, let's face it. Heck, it may never happen again. Then again, if Nadal continues to have health issues and is taken out early in slams then Murray indeed has a chance to reach more finals.
That said, I don't think Murray will be able to penetrate Federer's defenses and I think that Federer will blast him off the court, perhaps not as badly as the Us Open 2008, but still enough to send a clear message of who is boss. Obviously, most of us want a competitive match, we don't necessarily want a walk-over (I assume most don't want a walk-over but I could be wrong
). I'm sure some would like Federer to crush Murray badly and end his hopes in record breaking time.
Should be a good match. The thing that we as spectators have learned, time and time again, is that even when Federer plays poorly, he is a major threat to win in less than 5 sets. The Us Open 2009, Federer couldn't land a first serve and hit many DF's, yet with his poor serve, the match was on his racket and was ultimately down to the wire.
So in my opinion, if Federer serves well, it's over for Murray before it began. If Federer doesn't serve well, he still very well could win in 4 sets. Murray will have all the expectations in the world to win a grand slam in Australia. His experience in the 2008 Open should give him some confidence and he has improved since then.
Can't wait for this match.
