Ramos is now in Russian Federation with the Spanish squad as they prepare for the World Cup, but took time out to tweet in Spanish, hailing Nadal for his "dynasty on clay", calling him a "tennis legend" and "sporting hero".
Diego Schwartzman has come closest this fortnight to become the third man to beat Nadal in Paris.
Nadal struck first in an enthralling opening set, breaking Thiem's first service game to take a two-game lead but they were back on serve immediately as the Austrian hit back. He also beat the Spaniard in Buenos Aires in 2016.
Nadal won his sixth French Open title by defeating Federer once more in Paris.
Thiem, who was trying to become only the second Austrian Grand Slam champion after Tomas Muster's 1995 Paris triumph, played his part in the two hour 42 minute tussle but was unable to sustain the high-octane tennis needed to ruffle Nadal.More news: Origin Access Premier PC Games Subscription Service Announced

The Spanish world number one took his Roland Garros win-loss record to a jaw-dropping 86-2 as he captured his 17th Grand Slam title.
Nadal's career title count, which is now fourth on the all-time list, behind Jimmy Connors (109), Federer (97), and Ivan Lendl (94), and ahead of John McEnroe (77), whose tally he equalled and then surpassed with titles this year in Barcelona and Rome, respectively. He also won the US Open that year.
Nadal's win-loss record in Roland Garros finals, which is the best in a Grand Slam final among men in the Open Era, ahead of Sampras (7-0, Wimbledon), Djokovic (6-0, Australian Open) and Borg (6-0, French Open).
"It's awesome now, I can't describe my feelings", Nadal told the crowd on Philippe Chatrier Court moments after capturing his 17th Grand Slam trophy with a 6-4 6-3 6-2 victory. However, here a year ago in the semi-finals, Nadal destroyed Thiem, losing just seven games in a rout, but it is worth mentioning that Thiem triumphed in their last meeting in Madrid last month, in the quarter-finals.
- Victory on Sunday gave Nadal his 11th crown at Roland Garros from 11 finals.
That scenario loomed again with Nadal going to 2-0 in the second set on a fifth break point as Thiem fired another backhand wide.
