A second Wimbledon upset looked to be on cards last night as six-time champion Roger Federer struggled against French opponent Julien Benneteau.

The Swiss player lost the first two sets before turning things around in the second half of the match to win 4-6 6-7 6-2 7-6 6-1 and advancing to the fourth round.

After the match Federer said, despite being two sets to love down, he did not panic: "I tried to stay calm, and I was. It was like he's still such a long a way from the finish line that there is no reason right now to go crazy about it.

"Let's see how the third starts and then we'll take it from there. Like I said, I have been there so many times that I also know how to handle the situation."

Federer's close call came just 24 hours after Rafael Nadal's shock exit in the second-round on Thursday.

The Spaniard was defeated by little-known Czech Lukas Rosol 6-7 6-4 6-4 2-6 6-4, in one of tennis' great upsets.

Speaking about his fellow players loss, Federer saw the positive side: "Well, this is not against Rafa, but it was nice to see it's still possible. I think 15 years ago you had matches like this so much more often on the faster surfaces, that a guy could catch fire and just run through you.

"What this victory of Rosol does is give great belief for other players that they can beat the top guys, which I think is great, even though it might not be that great for me down the stretch. Hopefully not. But it's just great for the sport that it is possible."
