Real Madrid’s first LaLiga defeat of the season has changed the tone around the club. A 2-1 loss to Atlético Madrid at the Riyadh Air Metropolitano on September 20 placed the spotlight on José Mourinho’s project and created an early test of how the team responds to a setback. [1][3]

The defeat arrived after a highly encouraging opening sequence. Real Madrid had won four consecutive matches at the Bernabéu before the derby, including a 4-1 victory over Rayo Vallecano on September 12. They also beat Elche 3-2 away on September 15, meaning the Madrid side entered the derby with momentum and a perfect recent record in the league. [2][3]

Why the derby defeat matters

A first defeat does not, by itself, define a season. However, a Madrid derby carries a different level of scrutiny from an ordinary league fixture. Atlético’s victory gives Real Madrid an immediate competitive reference point and raises questions about whether the new project can deliver consistency when the opponent is able to disrupt its rhythm.

The most important issue now is not simply the scoreline. It is the reaction. Strong teams are judged not only by how they perform during winning runs, but also by the clarity and authority they show after losing. For Mourinho’s project, the next phase will be about restoring control, maintaining belief and ensuring that one derby defeat does not become a longer interruption to the team’s progress.

From early momentum to a response test

Real Madrid’s recent results show why expectations were high before the Atlético match. The 4-1 win over Rayo suggested attacking confidence at the Bernabéu, while the 3-2 success at Elche demonstrated that the team could navigate a more demanding away fixture. The derby, though, exposed the difference between building momentum and proving that momentum can survive the biggest domestic tests. [2][3]

That makes the next run of matches particularly important. The club does not need to overreact to a single loss, but it does need to provide evidence that the defeat was an isolated setback. A convincing response would help preserve the positive feeling created by the opening weeks. Another uneven performance would make the questions around the project more serious.

What supporters will be watching

  • Reaction in the next league match: Real Madrid’s performance after the derby will offer an early indication of the team’s resilience.
  • Control in difficult matches: The key challenge is turning strong home form and encouraging results into authority against high-level opposition.
  • Consistency rather than headlines: The project will ultimately be assessed across a sequence of matches, not one result in isolation.
  • Response to pressure: Mourinho’s teams are traditionally scrutinised for their organisation, competitive edge and ability to respond when momentum changes.

Why global attention is growing

Interest in Real Madrid remains especially strong because the club sits at the centre of global football conversation. Google’s U.S. trending-search data showed active interest in major football fixtures on September 25, including searches for “Portugal vs Wales”, underlining the wider appetite for high-profile matches and international football.

That attention means every Real Madrid result is examined beyond the Spanish league table. The derby defeat has become a talking point not only because Atlético won, but because it offers an early measure of how Mourinho’s project handles adversity under a global spotlight.

The next judgment on Mourinho’s project

Real Madrid’s response will now matter more than the defeat itself. The club’s opening results created a platform, but Atlético’s win has introduced the first serious test of the season. The task is to turn disappointment into a disciplined reaction, recover the authority shown in the earlier matches and demonstrate that the project can develop without being defined by one derby night.

For now, the evidence is mixed but limited: Real Madrid began strongly, won four straight matches at home, secured a narrow away victory at Elche and then suffered a 2-1 loss to Atlético. [1][2][3] The next performances will determine whether the derby was simply an early warning or the beginning of a broader debate about where Mourinho’s project is heading.
