Looking at how the bookmakers are pricing up the US Open, Roger Federer, Rafael Nadal and Andy Murray are all locked together pretty much as joint favourites.

I wonder if that is just because they are British odds: would you see the same thing with a bookmaker based in Spain or Switzerland?

If we start with Murray you have to say that he has played so well in the last few weeks. Players who suddenly click into gear after a spell when they have been lacking in confidence and form are always very dangerous - and that is where Murray is right now.

You can tell he feels like a man reborn. All

Congratulations
to Caroline Wozniacki for taking over from Serena Williams as the new world
number one.

She has
been the most consistent of all those players and deserves to be world number
one.

I say
consistently the best but I mean consistently the best out of those players
who've played a lot this year.

Is she the
best player in the world? No. Serena Williams is the best player in the world
and Kim Clijsters is probably second best.

But Wozniacki
has been the most consistent player and won enough big matches and has worked
so hard to get where she is, she deserves to be ranked number one in

When it came to last week's Shanghai Masters I wasn't at all surprised by anything that happened until the final between Andy Murray and Roger Federer.

I have to say I was taken aback by just how poorly Federer played in that decider. He does seem to have a thing about Murray away from the Grand Slams - but is that so significant? Maybe not.

In the final, though, Roger lost his way completely and it looked like he just didn't have the fight within himself to work it out; however I suspect that was just because it was 'only' a Masters event.

He was similarly under the cosh for a while at this

Looking at the ATP rankings, I have to say it is quite alarming to see all the same old faces knocking around - there really is nobody new coming through, which is quite extraordinary.

It is not an encouraging sign for the future of the game.

Look at somebody like Mikhail Youzhny (pictured) who has climbed back up to number eight in the world rankings - equalling his best ever ranking which he first achieved at the start of 2008.

Players don't just reinvent themselves. The fact that he is in the top 10 is very interesting and doesn't say a lot for the standard of tennis that is out there at

When a player struggles with a major injury, you never know how they are going to react.

Some people are never the same player again. I'm not sure Marat Safin ever fully recovered from his wrist injury, although obviously there were other issues as well. Discipline was very important with him but it seemed to me like the wrist was a major issue.

I think it'll take a bit of time for Juan Martin Del Potro to get himself back on track. The injury happened at just the wrong time. If you think what's happened since then, it couldn't have happened at a worse time for the Argentine.

It was great that

With Serena Williams out of the US Open the women's tournament is wide open.

I suppose a rational way to look at things would be to go with form, although often the US Open tends to be won by the class player rather than the form player.

There have been a few players in outstanding form recently and none more so than Caroline Wozniacki.

It is quite hard to analyse the young Dane at the moment but she keeps beating the players that are being put in front of her so it may be her time to taste Grand Slam glory after coming so close here in New York last year.

It might be a case that she is

Rafael Nadal's comfortable victory over Tomas Berdych came as no real surprise the way he is playing at the moment.

The Spaniard has proven himself to be the world's best player by some distance over the last two Slams and the rest are really an irrelevance at the moment.

I thought Berdych was a little nervous at the start and he didn't serve as well as he can.

I felt he had to win the first set to have any chance of winning the match and after he lost that, I was worried that he might capitulate a little bit.

To be fair, he did get it together in the second set and made things competitive

Rafael Nadal's victory over Andy Murray in the Wimbledon semi-final was the best individual performance I've seen in this tournament and possibly the best I've seen all year.

I was a little concerned about Nadal going into this match, and I know I'm not the only one; there were still some worries about his fitness and he hasn't always been at his best in the tournament so far.

However, there was absolutely no inclination about any injuries or lack of form whatsoever, and what Nadal produced was an unbelievable performance that was just fabulous to watch.

Murray on the other hand must be
