Serena Williams

It think it is fair to say that the first week of Wimbledon has been all about the men's draw, but Serena Williams finally gave fans of women's tennis some value for money against Zheng Jie.

After dropping the first set, many people felt she was in danger of suffering a similar meltdown to the one she experienced at Roland Garros - but she gritted her teeth and managed to polish off the victory against a dangerous opponent.

I picked Serena at the start of the tournament to win the event and this victory gives me hope that she can push on now and rediscover her best form.

She has an ability to

The last 24 hours at Wimbledon have produced two of the most dramatic first-week matches in recent years.

We've got so used to the top three having things their own way that it was a real surprise to see all three men dropping sets.

In Lukas Rosol, Rafael Nadal ran into an opponent who had the match of his life. What a display it was — the fifth set particularly was nerveless. He was inspired by the occasion, the atmosphere — you name it.

Nadal was not at his very best, but nor was he far from it. It was simply a freak result.

If you thought that would be a reminder to Nadal's rivals that

It was a mixed day for the British contingent at Wimbledon.

Andy Murray did okay; not spectacularly well, but he got the job done against Ivo Karlovic, a man whose best days might be behind him, but whose serving and sheer size makes him a real danger.

Karlovic certainly did not make life easy for him, but Murray was admirably patient, and moves on.

I think he'll probably be happy that possible third round opponent Grigor Dimitrov had to retire, allowing Marcos Baghdatis through instead.

Baghdatis will not be an easy match — he was a semi-finalist here back in 2006 — but like Murray's

Sam StosurThe biggest shock of the day for me - and the saddest result to see - was Sam Stosur losing to Arantxa Rus. That's not to take anything away from Rus, who played superbly well and deserves all the plaudits that she will receive, particularly for fighting back after being destroyed in the second set.

But the big question we're left with is this: why can't Stosur perform at Wimbledon? She's lost in the first round five times and in the second round the other four times she's played. It's a mystery.

When she was growing up the biggest tournament around for her, as it always is for Australians,

James Ward after winning his first-round match at Wimbledon 2012

James Ward raised more than a few eyebrows with his thrilling five-set win over Spaniard Pablo Andujar, not least because a lot of British fans had marked his Queen's run last year as a one-off. The British number two, ranked 173^rd in the world, overcame the world number 36 from Spain after trailing twice in an epic encounter.

While it will be chalked up as some scalp for Ward — comfortably his biggest victory in terms of context, and his first in a Grand Slam main draw — the Londoner will have known that he absolutely had to win this match.

Last year at Queen's, Ward surprised everyone by

Novak Djokovic started off very nervously against Juan Carlos Ferrero - but once he got into it, he looked good.

Not as good as Roger Federer, though. He was spectacular, albeit against an opponent in Albert Ramos who I don't think has ever won a grass court match!

Regardless of that though I've just got a sneaking feeling that Federer could win the tournament this year. The performance gap between him and Djokovic and Rafa Nadal has widened, it's true, but not on grass where the margins are so much finer.

I know he lost to Jo-Wilfried Tsonga last year, but Tsonga played the match of his

Serena WilliamsDespite what happened at Roland Garros, you have to look to Serena Williams as the clear favourite for Wimbledon.

Serena is still the best female tennis player in the world by some distance, provided she is fully focused and on top of her game.

What happened in Paris was extraordinary. A set to the good in her first-round clash with Virginie Razzano, Serena was 5-1 up in the second-set tie-break but she contrived to lose six points in a row. And in the third set she broke down, close to tears as she fell 5-1 down before losing it 6-3.

It was the first time she exited a Grand Slam in the

David Nalbandian realises what he has doneI was commentating at Queen's Club when David Nalbanian aimed an ill-advised kick at an advertising panel during the aborted final with Marin Cilic - an act that will, at the very least, cost him a seeding at Wimbledon.

Much like the majority of the spectators, I was initially unaware of what had happened: for about 10 minutes previously, the hot-headed Argentine had been shouting at himself and chucking his racquet in frustration every time something didn't go his way. So, when he lost that point to go a break down in the second set, most of us turned away in preparation for the next game.
