As Andy Murray prepares to take to the court for this quarter-final match against number 7 David Ferrer, let's take a moment to reflect on what we've just seen in the first two men's quarters at Wimbledon.
World Number One Novak Djokovic handled 31-seed Florian Mayer with seeming ease, posting a three-set victory (6-4 6-1 6-4). Meanwhile, Roger Federer was even more impressive, dispatching Mikhail Youzhny, seeded 29, 6-1 6-2 6-2.
I think we all expected both Nole and Roger to win their respective matches against these surpise quarter-finalists but with such ease?
Especially notable to me is the fact that Fed was able to put the pedal to the metal against Youzhny and keep it there for a full three sets. One of the Swiss master's recent failings had been his ability to maintain his focus through an entire match. Too often, he either starts slow and has to catch up or win the first set or two and then take a breather, giving his opponent a set or two before he ramps things back up.
But to see Federer's killer extinct on display in the quarters at Wimbledon says something about his focus and commitment in this Major. He's said right from the start that he feels he can win and now he seems to be taking his game to the next level as victory nears.
What does this mean for his upcoming semi-final match against Djokovic? I'm not sure. Djoko hasn't had any focus problems of late and his performance against Mayer indicates that he's in top form as well.
Grass is one of Federer's favourite surfaces. Fed is playing for a piece of history. He's also well aware that, if he can beat Djokovic, he won't find Rafael Nadal waiting for him in the final.
All that should suggest that Federer will be at his best in the semi on Friday.
My problem is, as big a fan of Roger Federer as I am, I am not convinced Fed's 2012 best is enough to beat Novak Djokovic's 2012 best, even on the grass of Wimbledon.
Two years ago, I'd have no problems picking Roger in this match. Today, I'm not so sure. I'll be cheering for him, absolutely; I'm just not sure he has the stuff to win it against a motivated, talented, fit and confident opponent like Nole.
