Andy Murray will be guarding against a major upset when he takes on another of the tennis world's lesser lights in Michael Berrer of Germany at the French Open on Saturday.
The pair will meet for the first time in the third-round match, scheduled second on Court Suzanne Lenglen at around 1200 BST, with Berrer facing the toughest test of his career.
Ranked 95th in the world, the 30-year-old from Stuttgart has already broken new ground by reaching this stage of a Grand Slam tournament for the first time since turning professional 12 years ago.
Indeed, Berrer has only managed three wins at any tournament once this year and faces a huge leap in class when he takes on the world number four, but whether the German is considered a dangerous outsider or an easy route into the last 16 makes little difference to Murray, who simply said: "If I play well, I'll give myself a good shot."
Murray's draw has certainly opened up invitingly during the first week with surprise defeats for the likes of Jurgen Melzer and Nicolas Almagro, and a victory on Saturday will see him face one of only two seeds remaining in his quarter - Viktor Troicki or Alexandr Dolgopolov.
When asked about a prospective meeting with Berrer, Britain's number one said he "has a big, lefty, single-handed backhand" and a similar contest to the opening two rounds in Paris looks likely.
Both Eric Prodon and Simone Bolelli were shot-makers and caused Murray moments of discomfort but, in the end, the Scot came through comfortably enough each time.
"I haven't dropped a set yet," said Murray. "I would have liked to have played a bit better in my first round but [on Thursday] I just wanted to get through.
"It was a match I would have been expected to win but it was a very tough one to come through, so I'm really, really happy I got through in straight sets because it could have been a lot different."
The French Open is widely considered to be the Grand Slam tournament that Murray is least likely to win, but the 24-year-old says his expectations for himself are the same in Paris as they will be at Wimbledon next month.
"Because I want to try and win the Grand Slams every time they come around now, I put pressure on myself at each one," said Murray. "The expectations I'm sure here are less than they are at Wimbledon but for me it's still the same."
Berrer watched the Briton's second-round win over Bolelli and was not especially encouraged by what he saw.
"He played solid," said the German. "He was down in the third set and he came back, as usual. I think, for him, he just has to win these matches, and it's the same against me.
"I'll be motivated. He's serving well, he's playing pretty flat, not too much spin. But I think on these courts it's fast. It suits his game."
Among those also in action on Saturday will be Rafael Nadal, Robin Soderling, Maria Sharapova and Victoria Azarenka, with the weather forecast suggesting a much-improved day after a cold and windy 48 hours in Paris.
Dutch 20-year-old Arantxa Rus will also return to the spotlight when she takes on Russian 25th seed Maria Kirilenko, having caused the shock of the tournament so far by defeating Kim Clijsters in round two.
