Nadal won the event in 2008.
"To win 10 Roland Garros titles is magical", added Nadal. "And I'm going to try to keep working hard to try to enjoy more attractive weeks".
"So my mentality was that I can not give Stan the chance to get back into the match".
Nadal was never threatened by his opponent, with Wawrinka possibly feeling the effects of the four and a half hours he needed to beat Andy Murray in the semifinals 48 hours earlier.
"Then I won Geneva and I reached the final of a grand slam".
This season, Nadal has compiled an ATP-best 43-6 match record with four titles. "He's playing the best he's ever played", the third-seeded Wawrinka told a news conference after watching Nadal collect the trophy.
"Nine here is probably hard".
He will step down after being at his nephew's side since boyhood. I guess it is not so bad, but it really depends on how you view his situation. "So I expect to see a strong Djokovic in the future". "When I watch him on TV I will be just as happy".
But there is no doubt that he is a big match player.
Nadal arrived at a Nike shop on Paris' famous Champs Elysees Avenue just after having posed with his trophy on a barge cruising the Seine River in the French capital, to the delight of a crowd of worldwide fans.
"Revenge is not part of my vocab".
'I hope that my knees will hold and that I have good preparation, ' he said, alluding to the fact that he has not progressed past Wimbledon's fourth round since 2011.
Wawrinka will be the third oldest victor of the men's title if he succeeds on Sunday.
Since losing in the 2011 final to Novak Djokovic he has not gone beyond the fourth round while a year ago he could not play because of the left wrist injury that curtailed his French Open.
The reigning champion lost to Dominic Thiem in the last eight at Roland Garros to continue what has been a hard 11 months for the previously dominant Serbian.
"It's motivation to other players because if it's possible for me, then it is for them too".
