World number three Roger Federer has expressed his relief after coming from behind to beat Gilles Simon in the fourth round of the French Open.
The Swiss avoided his earliest exit at a Grand Slam since 2004 to fight back from being 2-1 down in sets to win 6-1 4-6 2-6 6-2 6-3 at Roland Garros.
The victory marked Federer's 900th triumph of his career, and he was delighted to overcome a difficult challenge.
"I'm happy I found a way and took the right decisions and was able to sort of tidy up my play a little bit, not spray that many unforced errors, even though I don't think it was that bad," Federer told BBC Sport.
"You're always going to hit some against Gilles because he does a great job retrieving.
"Overall I'm very happy. I stayed calm under pressure, and it's always fun being part of matches like this."
Federer will meet Jo-Wilfried Tsonga in the quarter-finals of the tournament.
