Watch: Interview of 18-year-old Rafael Nadal after cracking top 10 surfaces online

Rafael Nadal earned his first ATP point more than two decades ago and is still going strong at the age of 35. Earlier this year, he won a record 21st Grand Slam singles title by triumphing at the Australian Open. He has won 20 of his 21 matches this year along with three titles.

The Spaniard debuted in the top 10 in 2005 after winning the Barcelona Open. He had clinched his first ATP Masters 1000 title in Monte-Carlo a few weeks prior.

@RafaelNadal after winning his 1st Barcelona & entering the Top10: "At the end I'm 18yo & I just try to enjoy on the court. I don't feel the media pressure, I feel the same guy as 3 months ago when I was #56, now I'm #7 and all that changes is a number, the rest is just the same" https://t.co/POylYT2oHD

Nadal arrived at the Conde de Godo that year in inspired form, having won 30 of his 36 matches and racked up titles in Costa do Sauipe, Acapulco and Monte-Carlo. At the Barcelona Open, the then 18-year-old did not drop a set, beating compatriot Juan Carlos Ferrero to win the title.

The win made Nadal one of the youngest players to break into the ATP top 10, which he has not exited in 17 years, the longest such streak. Speaking at a press conference after the accomplishment in 2005, the left-hander said that he felt "just the same" as when he was ranked No. 56 three months prior.

"At the end I'm 18, and I just try to enjoy on the court," Nadal said. "I don't feel the media pressure; I feel the same guy as three months ago when I was #56; now I'm #7, and all that changes is a number; the rest is just the same."

Incidentally, almost two decades later, another Spaniard, Carlos Alcaraz, triumphed at Barcelona to debut in the top 10. Interestingly, it was his fourth win in as many tournament finals and his third this year. That is something none of the Big 3 (Roger Federer (1-3), Nadal (3-1) and Novak Djokovic (3-1)) or any current member of the top 10 accomplished in their first four finals.

Speaking to the ATP, Alcaraz said he was "happy" to enter the top 10 at the same age (18) as his "idol" Nadal.

"I've always been a normal guy. I'm not scared of fame, I'm not going to change the person I am," Alcaraz said. "I'm happy to know that at 18 years old I'm in the Top 10, and to do it (at) the same age as my idol Rafa is impressive."

4 FINALS, 4 TITLES 🏆 🏆 🏆 🏆

🇪🇸 Carlos Alcaraz is 4-0 in tour-level finals—and 8-0 in sets—after defeating Pablo Carreno Busta, 6-3, 6-2, in Barcelona.

None of the Big 3 won their first 4 career finals, let alone all in straights.

Rafael Nadal's achievements as a teenager

Rafael Nadal is generally regarded as one of the best players in tennis history, with a lot of his success coming very early in his career.

The 35-year-old produced one of the best-ever years by a teenager in the sport's history in 2005. He won a whopping 11 titles in 2005, including one Grand Slam and four Masters 1000 titles.

Nadal successfully defended his Monte-Carlo, Barcelona and Rome titles the following year before turning 19. A week after his 19th birthday, he successfully defended his Roland Garros title too, beating Federer in the final.
