Real Madrid didn’t need to dominate Inter Milan to beat them.
It needed only a few moments.
Kylian Mbappé and Federico Valverde punished two costly mistakes in the opening 23 minutes before Thibaut Courtois repeatedly frustrated Inter as Real Madrid escaped with a dramatic 2-1 victory in its Champions League opener at the Santiago Bernabéu.
The scoreline tells one story.
The match itself tells another.
Inter controlled large stretches of the game, created enough opportunities to make Madrid uncomfortable and eventually pulled one back through Carlos Augusto.
Yet when the final whistle arrived, José Mourinho’s team had the three points.
And that contrast may be the most interesting lesson from Madrid’s first European night of the season.
Mbappé needed only one opportunity
Inter actually started the match looking like the more comfortable team.
The visitors controlled possession and tested Madrid early, forcing Courtois into action.
Then came the mistake.
Yann Bisseck lost possession under pressure, Brahim Díaz collected the loose ball and released Kylian Mbappé.
Mbappé didn’t waste the opportunity.
The French superstar finished clinically in the 14th minute, giving Madrid the lead with its first attempt of the match.
UEFA highlighted the efficiency of the moment in its post-match technical analysis, noting that Mbappé opened his 2026/27 Champions League account with Madrid’s first shot.
UEFA’s analysis of the match also identified Mbappé and Courtois as two of the decisive figures in Madrid’s victory.
For Mbappé, the goal continues an extraordinary relationship with this competition.
He entered the new Champions League campaign after finishing last season as its 15-goal top scorer.
It took him only 14 minutes to start scoring again.
Inter made another mistake — and Valverde made it 2-0
Nine minutes later, Inter gave Madrid another opportunity.
This one was even more damaging.
Goalkeeper Josep Martínez attempted to play his way out under pressure near his own goal.
Federico Valverde stole the ball and scored.
Twenty-three minutes had been played.
Madrid had a 2-0 lead.
According to Reuters’ match report, Inter controlled more than 64% of possession but was ultimately punished for two expensive defensive errors.
That’s what made this match unusual.
Inter could have the ball.
Madrid had the goals.
The statistics told a completely different story
At halftime, anyone looking only at the underlying numbers might have struggled to explain the score.
Inter had enjoyed approximately 70% possession and produced 12 shots to Madrid’s three in the first half.
Yet Madrid went into the dressing room leading 2-0.
That wasn’t because Inter created nothing.
Curtis Jones hit the crossbar, while Courtois had already been forced into important saves.
Madrid also had opportunities to increase its advantage.
The game increasingly became less about control and more about which team could survive the chaos.
That pattern continued after halftime.
Thibaut Courtois may have been Madrid’s most important player
Mbappé scored.
Valverde scored.
But Madrid might not have won without Thibaut Courtois.
Inter continued creating opportunities after the break and the Belgian goalkeeper repeatedly prevented the visitors from turning their possession into goals.
His performance carried additional significance because this was his 100th Champions League appearance.
UEFA’s technical observer singled out Courtois alongside Mbappé when examining the players who made the difference.
Valverde went even further after the match.
Despite scoring Madrid’s second goal, he said Courtois deserved the player-of-the-match recognition because of the goalkeeper’s extraordinary performance.
That tells you almost everything about the second half.
Madrid had the lead.
Courtois helped keep it.
Carlos Augusto finally gives Inter hope
Eventually, Inter found a way through.
With the match entering its final stages, Lautaro Martínez delivered the ball for Carlos Augusto, who scored in the 77th minute to make it 2-1.
UEFA’s official Champions League results confirm the final score and the three scorers: Mbappé, Valverde and Carlos Augusto.
UEFA’s official 2026/27 Champions League fixtures and results show Madrid beginning the league phase with three points.
But Carlos Augusto’s goal changed the atmosphere.
Suddenly, a match Madrid appeared to have controlled on the scoreboard became a fight to survive.
Inter pushed.
Madrid defended.
Courtois was called upon again.
The comfortable 2-0 advantage was gone.
Mourinho admits Madrid still has work to do
Winning the match doesn’t mean Real Madrid played the way José Mourinho wanted.
That distinction matters.
Madrid had moments when its pressing worked extremely well — both goals were directly connected to putting Inter under pressure — but it also spent long stretches without control of the ball.
Valverde acknowledged after the match that Madrid needs to improve and become clearer about what it wants to do on the pitch.
For a team with Champions League ambitions, that may be the biggest takeaway.
Madrid demonstrated that it can punish mistakes brutally.
It also demonstrated that giving an opponent this many opportunities can become dangerous.
Against Inter, Courtois was there to solve the problem.
That won’t always happen.
Mbappé remains Madrid’s ultimate difference-maker
There is another encouraging sign for Madrid.
Mbappé continues to score when the opportunities matter.
He finished last season as the Champions League’s leading scorer with 15 goals and needed only one meaningful opening to score his first of the new European campaign.
That’s exactly what elite Champions League forwards do.
Madrid may not dominate every opponent.
It may not always have the ball.
But having a player capable of turning one defensive mistake into a goal changes the calculation for every team facing them.
Inter discovered that within 14 minutes.
A strange victory — but three points all the same
Real Madrid’s own official match report emphasizes the team’s high pressing and the ability to protect its advantage after Carlos Augusto reduced the deficit.
The wider picture is more complicated.
Inter demonstrated that Madrid can be vulnerable.
Madrid demonstrated something equally important: it doesn’t necessarily need to be the better team for 90 minutes to win.
Two mistakes.
Two goals.
One outstanding goalkeeper.
Three Champions League points.
That was enough.
And if Mbappé continues converting chances with this kind of efficiency while Courtois continues producing nights like this one, Real Madrid will remain extremely difficult to eliminate — even on nights when the statistics suggest it should be struggling.
