Andy Murray will go from playing Rafael Nadal to taking on a student without a world ranking in Great Britain's Davis Cup clash against Hungary on Friday.
Six days after losing in the semi-finals of the US Open, Murray will meet Sebo Kiss at Braehead Arena, Glasgow.
Kiss, 27, achieved a career-high ranking of 531st in 2005, but now fits tennis around his law studies.
"I can play without pressure or expectation so we will see what's going to happen," said Kiss.
World number four Murray faced a similar opponent in Laurent Bram in the last tie against Luxembourg, also at Braehead, and on that occasion he did not lose a game.
But the Scot insisted he is not thinking of another 'triple bagel', saying: "It's always fun coming to the Davis Cup.
"I'm a bit tired and I only hit for the first time on the court on Wednesday so I won't expect to win with that scoreline but I'll just try to win the match."
Hungary are huge underdogs for the Europe/Africa Zone Group II promotion play-off, with their top player Adam Kellner withdrawing last week.
The world number 228 was struck down by a virus, while Marton Fucsovics, last year's junior Wimbledon champion, was left out due to personal problems.
That leaves Attila Balazs, ranked 262nd, as their only player with regular experience.
Murray became only the seventh man in the Open era to reach the semi-finals of all four major tournaments in the same year but found Nadal too tough in New York, just as he did at Wimbledon and at Roland Garos.
He said he was proud of his achievements this year and insists he remains in a good position to break his Grand Slam duck.
"I don't look back, I look forward and try to improve," Murray explained.
"You can spend a lot of time looking back and wondering at things you could have done. You learn from mistakes and then move on. This week is the first week of that process and I'll try to get better.
"I don't listen to what anyone else says at the moment because it's just not worth it.
"It's my goal to win a Grand Slam. That's what I want to do, so it's not a question that I've stopped asking myself."
The first rubber of the tie will see British number two James Ward take on Balasz, who Murray remembers as a "very good junior".
The 24-year-old, who has won six of his eight Davis Cup matches, said: "I've been playing well over the summer, especially in the States. I've played a lot of matches recently and I'm looking forward to playing again tomorrow."
The doubles rubber on Saturday will pit Colin Fleming and Ross Hutchins against Balasz and Kornel Bardoczky, with the British pair looking to continue their good form after reaching the quarter-finals at Wimbledon and the last four at the US Open.
