Following his triumph at the Paris Masters, Soderling arrived in London as the man in form, but lost his opening game of the tournament in straight sets to Andy Murray.


However, the Swede managed to keep his hopes of reaching the knockout stage alive by battling past David Ferrer to move joint second alongside the Brit, who was crushed by Federer.


"I served very well, especially in the first set. But it was tough. It was a close match, two really tough sets." the 26-year-old Swede said afterwards.


"I'm lucky that I won. I still feel that I have a lot of things that I can improve. Hopefully I can do that in one or two days and play a good match in my next match."


As things stand, Murray superior head-to-head record against Soderling means the Brit would qualify. The Second criteria is percentage of sets won, followed by percentage of games won.


Beating the Swiss will be by no means be an easy task, Federer has looked unbeatable so far, breezing past both Murray and David Ferrer in less than three hours to ensure his place in the next round.


"Andy has beaten me the last few times so I'm surprised how clean the score was today, but I don't think Andy played his best match, that is for sure," Federer said following his latest triumph.


"I'm surprised it went so well, almost a bit shocked to be honest. But obviously I'm happy I'm playing so well."


Soderling may be hoping to face a complacent Federer in their upcoming match, but it is unlikely that arguably the best tennis player of all time will be anything but masterful once more.
