There may not be a more important domestic fixture in the world than El Clásico, the clash between bitter rivals Real Madrid and Barcelona.
Meetings are nothing short of intense and the star power is often overwhelming. In this LaLiga season's first Clásico on Saturday, a new star makes his debut -- Real Madrid forward Kylian Mbappé. The Frenchman -- as well as his teammate Endrick and Barcelona's Dani Olmo -- has yet to appear in the iconic match.
Barcelona sit first place in the table and enter Saturday three points ahead of Madrid, having won nine of its first 10 LaLiga matches. Both sides are coming off wins in the UEFA Champions League earlier in the week -- Madrid had a dramatic comeback against Borussia Dortmund, while Barcelona crushed Bayern Munich.
Whether or not Mbappé, Endrick or Olmo can live up to the hype of past debuts from other big names, the fixture will surely deliver.
Here's a look back at how notable players fared in their Clásico debuts since 2000.

Lamine Yamal, Barcelona, 2023
Stats: 21 minutes, 1 shot
Result: 2-1 Real Madrid win
Then 16 years old, Yamal came off the bench in the 76th minute in a 1-1 contest, becoming the youngest player to ever appear in El Clásico. Yamal admitted that while he'd never been nervous in a game before, there were nerves for his debut.
Though his performance on the pitch was limited, Yamal's inclusion signaled a new era for Barcelona. One year later, he's one of the most important players for the Catalan side.
Jude Bellingham, Real Madrid, 2023
Stats: 97 minutes, 2 goals, 2 shots
Result: 2-1 Real Madrid win
After his €103 million move, the English midfielder made his presence known early for Real Madrid, notching goals in his first four LaLiga fixtures. But his performance against Barcelona took him to another level.
After Ilkay Gündogan gave Barcelona an early lead, Bellingham responded with a strike to equalize in the 68th minute. Bellingham found the net again in the 92nd minute, propelling Real Madrid to a dramatic win.
Jude Bellingham taps home the goal to give Real Madrid a 2-1 lead in stoppage time against FC Barcelona.
Vinícius Júnior, Real Madrid, 2019
Stats: 95 minutes, 6 shots
Result: 1-0 Barcelona win
Real Madrid's signing of Vinícius made him the club's second-most-expensive player to arrive from the Brazilian league. However, his debut season included just nine starts for Madrid, one of which came in El Clásico.
Vinícius flashed his potential with six shots, three fewer than Barcelona's entire team. The Catalan side was victorious, however, thanks to a first-half goal from Ivan Rakitic.
Gareth Bale, Real Madrid, 2013
Stats: 61 minutes, 2 shots
Result: 2-1 Barcelona win
Signed only a month and a half before El Clásico, Bale left Tottenham for Real Madrid on a then-world-record fee -- €100m.
Bale struggled in his debut, taking two shots before being replaced by Karim Benzema in the 61st minute. Barcelona entered the matchup in strong form and carried it to the pitch, winning 2-1.
Neymar, Barcelona, 2013
Stats: 85 minutes, 1 goal, 1 assist, 3 shots
Result: 2-1 Barcelona win
Speaking of high-priced transfers -- Neymar's move to Barcelona in 2013 made him the most expensive transfer ever from the Brazilian league. More than 50,000 fans welcomed the star at Camp Nou for an unveiling of arguably the most exciting young talent in the world.
Neymar's Clásico debut included similar theatrics. He netted a goal in the 19th minute, then assisted Alexis Sánchez in the 78th to cap off a memorable performance.
David Villa, Barcelona, 2010
Stats: 78 minutes, 2 goals, 3 shots
Result: 5-0 Barcelona win
Signed earlier in the summer for €40m from Valencia, Villa came to Barcelona in top form, fresh off a World Cup win with Spain.
That form carried over as he had a key role in one of the most famous Clásico games of all time. Villa netted two goals in three minutes, sending the Camp Nou fans into a frenzy and shocking Madrid en route to a rout.
Zlatan Ibrahimović, Barcelona, 2009
Stats: 42 minutes, 1 goal, 1 shot
Result: 1-0 Barcelona win
The Swedish striker came to Spain after a dominant 29-goal, 11-assist campaign with Inter Milan. 60,000 fans welcomed Ibrahimović at a Camp Nou unveiling, and he made their support worth it against Madrid.
With the game goalless, Ibrahimović came on in the 51st minute and scored the decisive goal five minutes later with his first, and only, shot of the match -- a one-touch half volley. Talk about an impact sub.
Cristiano Ronaldo, Real Madrid, 2009
Stats: 66 minutes, 3 shots
Result: 1-0 Barcelona win
Ronaldo was the reigning Ballon d'Or winner and FIFA World Player of the Year, making him arguably the best player in the world in 2009. As is at times customary for Real Madrid, they set a then-world record transfer fee of £80m to sign Ronaldo from Manchester United.
He scored in each of Madrid's first four LaLiga matches, but was quiet against Barcelona, being subbed off for Benzema in the second half.
Lionel Messi, Barcelona, 2004
Stats: 90 minutes, 1 assist, 7 shots
Result: 3-0 Barcelona win
Messi's rise from Barcelona's academy to the first team coincided with legendary players such as Ronaldinho and Xavi being staples of the starting 11. However, he fit in nicely in his first Clásico.
At 17 years old, Messi assisted Barca's first goal -- a strike from Samuel Eto'o -- and took seven shots in a comfortable win.
