Roger Federer's thrilling comeback win over Gilles Simon has set up the second week of the French Open perfectly.

In the women's draw, Serena Williams is rolling back the years; the outcome of her matches aren't in doubt, it appears - it's simply a matter of how long her opponents can stay on court for. Serena has performed poorly at the French for a number of years - her only title coming way back in 2002 - so I'm sure she'll be doubly determined to finish off the job. I was surprised at the start of the competition to see Laura Robson lose to Caroline Wozniacki by so wide a margin. Such has been Laura's progress that we've come to expect her to raise her game in the big matches and be really competitive. But every match that she plays is the next step on a steep learning curve and at least the most difficult part of her year is now out the way and now she can look forward to playing on a surface that she is very, very comfortable on. I do think that she needs to get her coaching situation sorted, though; it would be hugely beneficial if she could find someone to replace Zeljko Krajan as soon as possible. If it's not done now, though, I think it will be best to wait until after the grass-court season. Either way, I'm sure she'll produce some exciting tennis this summer.
