No other player has won the same Grand Slam title as many times as his dozen at Roland Garros, Sunday's triumph taking him past Margaret Court's 11 Australian Open titles.
Highlights - Nadal made to work by Thiem for historic 12th title at Roland Garros
It was pointed out to the 33-year-old Spaniard a few hours after he walked off court that he is now just two behind 37-year-old Federer's record haul, with time on his side.
Nadal, however, was content to enjoy the moment.
"Being honest, I am not very worried about this stuff, no?" Nadal told reporters.
You can't be frustrated all the time because the neighbour has a bigger house than you, or a bigger TV or better garden. That's not the way that I see the life, you know.
Nadal has suffered more injuries throughout his career than Federer and Serbian world number one Novak Djokovic, who is third on the all-time list of major winners with 15.
Even this season he has been plagued with knee injuries, being forced out of his Indian Wells semi-final with Federer before withdrawing from Miami.

His knees were still bothering him as his happiest hunting season began on the European claycourts he has owned.
I lost, I think, around 15 or even more Grand Slams in my career for injuries. So it has been difficult.
Watching him repel the swashbuckling Thiem on Sunday with the kind of intensity and sheer willpower that has marked his career, it was hard to believe that just a few weeks ago in Barcelona he was suffering a crisis of confidence.
Thiem beat him in straight sets in Barcelona and Nadal said it was at that tournament he realised he needed to change his mentality.

"Mentally, I lost a little bit of energy, because I had too many issues in a row," he said. "Mentally I was not enjoying. Too much worried about the health and, being honest, too negative.
After the first round in Barcelona, I was able to stay alone for a couple of hours in the room and think about it and think about what's going on, what I need to do.
"One possibility would have been stop for a while and recover my body. And the other was change drastically my attitude and my mentality to play the next couple of weeks."
