The result brings Jose Mourinho's side to within three points of the La Liga table leaders, while halting Barcelona's impressive momentum under head coach Hansi Flick in what proved to be a pulsating encounter in Catalonia.

Mbappe proved to be the difference maker by netting twice during the contest, culminating in an 87th-minute winner that sent the visiting bench and travelling supporters into wild celebrations inside the stadium.

The decisive moment arrived late in the game when midfielder Eduardo Camavinga delivered a precise cutback following some sublime individual skill from England international Jude Bellingham in the build-up.

Mbappe was on hand to apply the finish, slotting past the goalkeeper to secure a famous triumph that marks Real Madrid's first victory away at their great rivals in Barcelona for three years.

The visitors had initially broken the deadlock in the 41st minute through a somewhat fortuitous opening goal when Barcelona defender Gerard Martin inadvertently slammed a clearance straight off Mbappe and into the net.

That bizarre breakthrough came at the end of a fine team move by Real Madrid, who showed a willingness to go toe-to-toe with their favoured hosts right from the opening whistle of the fixture.

Barcelona, who entered the match on the back of strong domestic form, managed to respond after the interval when Brazilian forward Raphinha drew the defending champions level in the 61st minute.

Pedri engineered the opening with a clever reverse pass into the path of Raphinha, whose instinctive snapshot beat goalkeeper Andriy Lunin despite the Ukrainian getting a hand to the effort.

Buoyed by the equaliser, the hosts pressed forward in search of a second goal, with young winger Lamine Yamal coming close when he skipped past several challenges before clipping a shot narrowly wide.

Lunin also had to be at his best to keep Real Madrid level, producing a magnificent save to claw away a powerful header from Martin following a corner kick during a sustained period of Barcelona pressure.

Despite the home side controlling large spells of the second half, Real Madrid maintained their defensive organization and remained a threat on the counter-attack throughout the high-octane encounter.

Earlier in the first half, both sides had traded attacking opportunities in an end-to-end spectacle watched by a global audience, with Arda Guler and Raphinha both testing the respective goalkeepers.

Mbappe had also threatened earlier in the half with an acrobatic scissor-kick that flew over the crossbar following a surging team move initiated by a strong defensive tackle from Bellingham.

A major flashpoint occurred shortly before the hour mark when defender Joao Cancelo caught Yan Diomande with his studs on the calf, though no retrospective or on-field punishment was issued.

Real Madrid head coach Jose Mourinho expressed his satisfaction with the performance and the final outcome, praising the courage and discipline shown by his players against a formidable opponent.

The Portuguese manager told reporters after the match that his squad executed their game plan effectively under intense pressure, maintaining their composure even after Barcelona had equalised in the second half.

Mourinho also highlighted the competitive nature of the fixture, emphasizing the quality displayed by both teams in what he described as a high-level match fitting of the historic rivalry.

For Barcelona, the defeat represents a significant setback after a strong start to the campaign that had featured a long winning streak in domestic competition before a recent stumble in Europe.

Head coach Hansi Flick admitted his side lacked their usual freshness during the first half, though he took some encouragement from an improved display after the interval once they had equalised.

Flick noted that defeats are an inevitable part of the football season and stressed the importance of a strong reaction as his team looks to maintain their position at the summit of the standings.

Mbappe, reflecting on his decisive contribution, emphasized the collective effort required to secure such a vital result away from home in one of world football's most demanding fixtures.

The forward told club media that the victory sends an important message regarding their championship ambitions, though he insisted that the title race remains wide open with a long way left to play.

Real Madrid will now look to build upon the confidence gained from this statement win as they navigate a busy schedule of domestic and European fixtures in the coming weeks and months.

Ironically, that longstanding record was established by Real Madrid themselves more than five decades ago. Now, it is Jose Mourinho's Madrid side who hold the key to stopping their bitter rivals from rewriting the domestic history books on home soil this weekend.

The Catalan giants head into this blockbuster fixture following a midweek setback on the continental stage. Barcelona suffered a 4-2 defeat against Paris St-Germain in the Champions League, exposing certain defensive frailties that their upcoming opponents will be keen to exploit.

That European defeat gives Mourinho's men the ideal psychological opening to capitalise on any lingering doubts. Real arrive in high spirits after securing consecutive 4-1 victories against Sevilla and RB Leipzig in their most recent domestic and European outings.

Despite those resounding wins, Real manager Mourinho insisted that past performances hold little weight ahead of a fixture with such immense global magnitude. The veteran Portuguese coach acknowledged the strong dynamic within his squad while underlining the unique nature of the encounter.

"We are in a good dynamic, we play well, we score goals, but the Clasico is different. What we have done before has no influence," Mourinho told reporters ahead of the match. "There are other important matches in the world, but this is the only Clasico, the world stops."

The fixture will showcase immense star power, featuring six players who were nominated for this year's prestigious Ballon d'Or award. Barcelona boast young sensation Lamine Yamal, defender Pau Cubarsi, and midfielder Rodri among their ranks.

Meanwhile, the visitors travel with their own stellar contingent of nominees, including French striker Kylian Mbappe, versatile defender Marc Cucurella, and England midfielder Jude Bellingham. These high-profile names are set to engage in several compelling individual battles across the pitch.

One of the standout duels could see Cucurella tasked with trying to nullify international team-mate Lamine Yamal down the right flank. Further back, central defender Cubarsi renews his acquaintance with Mbappe following their meeting in the World Cup semi-final.

Mbappe has enjoyed a prolific start to the campaign since moving to the Spanish capital, netting 12 goals in his first 12 appearances across all competitions. His pace and clinical finishing in the final third represent Real's primary threat in the absence of the suspended Vinicius Jr.

In the center of the park, a fascinating tactical battle looms between Rodri and Bellingham. Both players dictate the tempo for their respective teams and excel at winning crucial second balls in congested midfield areas.

Real currently sit third in the La Liga standings, trailing table-toppers Barcelona by a six-point margin. Mourinho admitted that his squad is still very much a work in progress as they adapt to his tactical demands following his arrival earlier this season.

"We've been together for three months if you take away pre-season and international breaks," Mourinho explained when discussing his team's development. "The players are still getting to know me and the way I do things."

Addressing reporters, the Real manager also dismissed suggestions that he would completely alter his tactical setup specifically to deal with Lamine Yamal. While acknowledging the teenager's supreme ability, Mourinho emphasized that his side would stick to their core principles.

"He's a great player, we respect great players. We aren't going to completely change things. We won't forget the way we do things," Mourinho added, projecting his trademark confidence by stating that Madrid under his guidance ultimately collect silverware.

On the other side of the technical area, Barcelona boss Hansi Flick expressed full confidence in his players' ability to bounce back from their midweek disappointment. The German manager emphasized the sheer scale of the occasion during his pre-match media conference.

"The players have recovered and they're ready for this game," Flick told journalists. "El Clasico is different, the best match our sport has to offer. Everyone will be watching. You can only win three points, but it's so much more than that."

Flick was quick to praise Madrid's formidable attacking prowess and warned his squad against any form of complacency. He highlighted the visitors' quality in advanced areas and stressed the vital importance of defensive organization.

"I expect a very confident team," the Barcelona manager noted. "Real Madrid is a great club with great players and a great coach. They have players with great quality in the final third. They've shown that in recent matches. We have to be careful and prepared."

Barcelona have been irresistible in attack during the opening months of the season, finding the back of the net 50 times across their first 12 fixtures. However, defensive solidity remains a lingering concern for the champions, who have already conceded 15 goals.

Flick specifically pointed to the high defensive line that his team deploys and the necessity of maintaining optimal spatial awareness. Without the ball, the German coach wants his players to stay compact and manage distances effectively to thwart rapid counter-attacks.

"Our positioning is key, both with and without the ball," Flick stated. "Without the ball, we need to maintain the right distances between players and stay compact, which is especially important when playing with such a high defensive line."

Set-pieces could also prove decisive at Camp Nou, with Flick identifying Real's proficiency in dead-ball situations as a major hazard. The Barcelona coach acknowledged that his team's defending from such scenarios must improve drastically compared to their outing in Paris.

For Real Madrid, a successful afternoon likely depends on disrupting Barcelona's customary possession rhythm. By maintaining a disciplined defensive block and launching swift transitions into open spaces behind the home side's advancing full-backs, Mourinho's men hope to cause damage.

Furthermore, the visitors will need to capitalize efficiently on any scoring opportunities that materialize over the course of the 90 minutes. Clinical finishing will be paramount if Real are to silence the Camp Nou crowd and reduce the gap at the summit.

A victory for Barcelona would not only secure an unprecedented slice of league history but also extend their lead over Real Madrid to a commanding nine points. Such an outcome would firmly establish the Catalan club as runaway favorites for the domestic crown.

Conversely, an away win would trim Barcelona's advantage down to just three points, breathing new life into the title race. It would also provide Mourinho's side with a massive psychological lift as they continue their pursuit of silverware under the Portuguese tactician.
