Rafael Nadal's record tally of 12 French Open titles will still be talked about "in 200 years", says former British number one Greg Rusedski.
Nadal, 33, is the first player to win a dozen singles titles at the same Grand Slam.
The Spanish second seed beat Austria's Dominic Thiem 6-3 5-7 6-1 6-1 in Sunday's final at Roland-Garros.
"This is the unbreakable record," former US Open finalist Rusedski told BBC Sport.
Nadal's third successive win on the Paris clay moved him clear of Margaret Court's tally of 11 Australian Open titles.
The Spaniard is only the second player to win the same tour singles event a dozen times, with Martina Navratilova having won 12 titles at Chicago between 1978 and 1992.
