"The more things change, the more they stay the same."

Roger Federer is OK, hard courts will favour him – Ivo Karlovic proved that wrong. Rafael Nadal can't be beaten in his current form – Novak Djokovic proved that wrong. Djokovic will make a strong return after Wimbledon – Andy Murray proved that wrong.

So you say Andy is the best right now? Not so fast, my friend. Let's start with Fedex – Federer looks far from OK. Is he a great player? No doubt! Will he win Olympics and US Open? Can't say, though you can bet that he will make the semis.

He actually joked that he was on a "one-game winning streak" after his first match in Cincinnati, and then after his loss to Karlovic, he insisted: "The bigger picture is the Olympic Games and the US Open. Those are the places where I want to win."

Really Roger! I mean, after you lose a tournament you talk about the next one as if nothing happened in the one that you just lost! As one of your fans, I am getting concerned that at this rate, if you lose at the Olympics and the US, you will say: "This was a good year but my focus is on regrouping for 2009."

I think instead of focusing on anything else, he should only focus on his confidence level – both over-confidence as well as bouts of low confidence. This may sound absurd, but he needs to make sure that he's confident of closing – closing a point, a game, a set and a match.

He needs to play tight, even play safe like how every player does, including Nadal & Co, when they know that a single point can tip the match one way or the other, but since Roger refuses to do it, my assessment is that he will remain in trouble. In my mind he's still the greatest but still the most obstinate in not making the badly-needed adjustments during a match. He seems either over-confident or starts playing over-anxiously and then seems surprised that he lost. Whew!

Nadal – the guy is so much improved in his determination, his game and knowing that other players get mentally fickle when he makes those unexpected results – he's truly unbelievable. You can say so many things about this guy – how he is winning on all surfaces, how focused he is on his pursuit of No.1 position and how he has taken his game to next level, but there is no need. Everyone can see it clearly, so...

Does he deserve No.1 ranking? Absolutely. Is he self-effacing and humble? Yes. But here's my thought: Is his game as complete as Federer’s? I don't think so.

C'mon, don't pretend to be shocked. Roger on a good day is still ahead of Nadal. Nadal surely is snapping at his heels - in fact, he has taken world No.1 spot, but Roger is Roger.

Djokovic – he seems to be getting his groove back. Looks better prepared and determined to retain his No.3 position after the stunning loss to Marat Safin at Wimbledon, but his stamina is not the same as others in the top 10. He can win his matches on skill and talent but I'm gonna say that every time a match goes to four sets or more and his opponent retains the mental poise, Djokovic can be defeated. In fact, he may have tough time retaining his No.3 position for too long.

Andy Roddick – can you step it up and make a comeback? I know it looks impossible right now, but I do believe that the guy has got the game. He's in a bit of Roger situation. Over-anxious in his matches most of the time.

And now to the latest sensation – Andy Murray! Man, isn't he showing glimpses of Nadal in his game? Unbelievable returns, great passing shots, speedy running all over the court. If anyone can take the tag of most improved player in the top 10, it has to be this kid.

What I like about him is the same humble streak as Nadal – realistic in what he says. So Andy is a great winner but I'll repeat what I said at Wimbledon time – this kid is OK when he wins the first set but when he doesn't, Lord have mercy!

Not to take anything away from him, but if you watched the Cincinnati final, you could see that Djokovic in the second set was trying not to lose and not playing to win. A couple of good shots from Novak and Andy's body language hit a downturn. In fact, it looked more and more that it would be tough for Andy to win if Djokovic could get his breath back.

Again, I think Djokovic lost rather than Andy won, but in the end I was happy with the result and for Murray. He has put in the hard work and it is paying off. I still think, though, that Andy has a long way to go – the good news is he can.
