From joining Rafael Nadal's academy as a promising teenager to making the final of the French Open: Casper Ruud's incredible journey

Casper Ruud will play his maiden Grand Slam final against Rafael Nadal on Sunday. The Norwegian will try to deny the Spaniard his 14th title at the tournament.

Many players, including Roger Federer, Novak Djokovic, Stan Wawrinka and Dominic Thiem, have tried to best the Spaniard in the title clash in Paris and all have failed. The Mallorcan has a flawless 13-0 record in Roland Garros finals, a record he will try his best to improve on Sunday.

The Norwegian knows as much, acknowledging the enormity of the task ahead of him at his press conference ahead of the summit clash.

"To play Rafa in a Roland Garros final is probably the greatest challenge there is in this sport. I believe he's 13-0 in the finals, so just shows that it might sound like an impossible task. But of course I will give it a shot like the other 13 people before me have done," Ruud said.

But Ruud has one advantage that none of the others before him did -- he has trained in the 21-time Grand Slam champion's own backyard. In 2018, Casper Ruud was a teenager with lots of promise and was in the process of honing his skills. He landed at the Rafa Nadal Academy in Manacor to train with the coaches and gain some insight about his game.

The World No. 8's father Christian Ruud recalled the experience in a recent interview, saying that they were recruited by the World No. 5's agent after seeing his son's potential. Adding that it was an arrangement they were happy with, the former ATP player said he hoped the relationship would continue for years to come.

"When Casper Ruud was [a teenager], Carlos Costa came to me during the French Open and was wondering if he wanted to come [to the Rafa Nadal Academy] and try it out," Christian Ruud said. "It was a big step for us. We are very happy with our relationship with them, and hope it will continue for many years."

The 23-year-old himself has made no secret of his adulation of the former World No. 1, hailing the southpaw for the humility he displays despite being the holder of some of the biggest achievements in the sport.

I try to learn from [Rafael Nadal] every time I get to practice with him. On the court and off the court, I think he's a very good example of how an athlete should behave, the values he has," Ruud said. "It's motivating to be around him because you're talking about a guy who has won everything there is to win and still plays today like it's the first time he's playing on the center court."

"We have played some practice sets at the academy but pretty much has always beaten me" - Casper Ruud on training with Rafael Nadal

From Casper Ruud's accounts, he has pretty much never beaten Nadal even in their practice matches

Casper Ruud appeared at ease about the prospect of facing Rafael Nadal in the all-important clash in Paris. He revealed at the press conference that he has barely won any of the practice matches he has played against the 36-year-old back at the academy. The Norwegian joked that he let Nadal win because he was playing in the Spaniard's academy.

"We have played some practice sets [at the academy]. And, yeah, it's been, I don't know honestly, but [Rafael Nadal] always pretty much has always beaten me. There's been some close sets, 7-6, 7-5, but it always goes his favor. But it's because we are playing in the academy and I want to be nice to him and give him [the win]," Ruud joked.

On Sunday, the World No. 8 cannot afford to be that "nice." With a record-extending 22nd Grand Slam title on the line, the Spaniard will come into the contest all guns blazing.

Ruud will be looking to make history of his own. A win against his idol would make him the first ever Norwegian to win a Grand Slam title. However unlikely it appears on paper, Ruud made it very clear that he will give his very best in the title clash -- perhaps something they teach best at the Rafa Nadal academy.
