Real Madrid opened their Champions League campaign with a 2-1 win over Inter, but had to work hard to protect the result at the Bernabeu. Mbappe and Federico Valverde established a two-goal first-half advantage, while Thibaut Courtois became crucial as the visitors increased their pressure after the interval.
Both Madrid goals followed errors in Inter's handling of the ball. Brahim Diaz won possession and released Mbappe to finish past goalkeeper Josep Martinez. Valverde then closed down Martinez as he hesitated in possession, causing Inter to concede again close to their own goal.
The visitors continued creating chances despite the deficit. Courtois made repeated saves, while Madrid failed to finish counterattacks that could have settled the game earlier. Carlos Augusto reduced the gap in the 77th minute from Lautaro Martinez's low cross, setting up a tense closing period.
Inter had 21 shots to Madrid's 16, although the hosts recorded eight on target, one more than their opponents. The figures reflect an open contest in which taking key opportunities made the difference. Madrid retained the win, but improving control remains a task before their next European trip to Roma.
