Andy Murray was taken back to one of the worst performances of his career as he prepared for Saturday's third-round clash with Philipp Kohlschreiber at the French Open.
It is likely to be a tough battle against the 28th seed but it would be a major surprise if the match went anything like their only previous meeting.
That came in Monte Carlo four years ago when Kohlschreiber won 6-2 6-1 in little more than an hour and Murray was jeered off court.
The Scot said afterwards: "I was just rubbish. I played a rubbish match."
He appears to have blanked the worst details from his mind, saying : "I remember not playing particularly well. I was very disappointed after the match.
"Over the years I have had a few matches like that in Monte Carlo where I've lost fairly comfortably. I lost to Stan (Wawrinka) last year very quickly, as well.
"At the beginning of the clay-court season I have had some tough matches over the years, so I don't remember a whole lot about it in terms of exactly what happened during the match. It just wasn't a pleasant memory for me."
There is no doubt Kohlschreiber represents a major threat to Murray's aspirations of going a long way in the tournament.
The German has reached six ATP Tour finals on clay compared to none for his opponent, and won his third clay title on Saturday in Dusseldorf.
Kohlschreiber, who cited clay as the surface on which he would most like to play Murray, is no stranger to big matches at grand slams and is the last player to beat Novak Djokovic before the quarter-finals of a major.
That came here in 2009, while he won sets against both Djokovic and Rafael Nadal in grand slams last year.
He said of his chances: "It all depends on his level of play, I would say. If the big guys are confident and they win many matches, they're going to be tough to beat.
"Obviously I'm also on a very nice run at the moment, so it's the best chance at the moment to play against the big guys.
"For sure he's the favourite in this match, but I'm going to try everything and fight from the first to last point. I'm going to enjoy this match."
Another top seed fell in the women's tournament on Friday as Agnieszka Radwanska was beaten by 21-year-old Croatian Ajla Tomljanovic.
It is the first time in the Open era that all the top three women's seeds have gone out before the fourth round at any grand slam.
In the men's singles, Djokovic and Roger Federer were both taken to four sets but survived and on Saturday it is Nadal's turn when he takes on Argentinian Leonardo Mayer.
