Real Madrid beat RB Leipzig 4-1 at home on Wednesday to maintain a perfect Champions League record — three wins from three — with goals from Bernardo Silva, Arda Guler, Kylian Mbappe, and Yan Diomande. The performance was Madrid's most complete European display this season, and it arrives at the best possible moment: four days before a La Liga Clásico against Barcelona. The first half was cagey. Leipzig created the first real chance — Romulo Cardoso forcing a low save from Thibaut Courtois — and Madrid looked stilted until the final minutes, when Federico Valverde cut back for Guler, whose shot was saved but not cleared. Bernardo Silva darted in to prod home his first goal for the club since his summer move from Manchester City. It was the kind of poacher's instinct Silva rarely showed at City, and it opened the floodgates. Guler doubled the lead seven minutes into the second half, finishing a sequence that showcased Madrid's attacking connectivity: Jude Bellingham crossed deep, Mbappe nodded across goal, and Guler held off a defender to turn it home. Mbappe then scored the goal of the night, bending a shot from the edge of the box after Diomande — on as a substitute for Vinicius — pulled the ball back. It was vintage Mbappe: one touch to set, one strike to finish. Vinicius's evening told a secondary story. Serving a four-match La Liga ban, he started on the left and was functional without being electric, an improvement on a poor outing against Roma but not the performance of a player in peak form. He looked visibly frustrated when substituted with 20 minutes remaining, knowing he won't play again until November 4 against AEK Athens. The contrast with Diomande — who came on and immediately scored a thunderous volley from Brahim Diaz's cross for his third goal in four appearances — was stark. Mourinho's tactical choices are hardening into a pattern: Valverde at right-back, Camavinga and Silva in midfield, and a willingness to rotate attacking talent based on form rather than fee. Diomande, Madrid's record 140 million-euro signing, has been benched repeatedly but responds with decisive impact off the bench. Leipzig's consolation goal, Tidiam Gomis firing past Courtois after Dean Huijsen switched off, was a reminder that defensive concentration remains a work in progress. The broader Champions League context matters. Barcelona lost at Paris Saint-Germain on Tuesday, meaning Madrid head into Sunday's Clásico as the only Spanish club with a perfect European record. For a team without a major trophy in two seasons and a shaky domestic start, this run of four consecutive wins across all competitions represents stabilization, not dominance. The squad is deep, the attacking options are real, but the question remains whether Mourinho can sustain this form when the schedule compresses. This was a match that rewarded patience — a slow first half giving way to a ruthless second — and it showcased the depth of a squad that can absorb Vinicius's absence and still produce four goals against Bundesliga opposition. The Clásico will be the real test.
