Bayern Munich secured a crucial 4-0 victory in the Bundesliga Round 21 on Sunday, maintaining their perfect record with a clean sheet against Schalke 04. The performance was led by star striker Thomas Müller, who scored twice from close range, while key midfielders Kevin de Bruyne and Leroy Sane also added goals. In addition, young talent Thomas Müller's younger brother Julian made his debut as a substitute.

Müller started the scoring with a well-timed header after receiving a pass from De Bruyne. The Bayern captain then extended his tally with a powerful shot from just outside the box, which was saved by Schalke goalkeeper Simon Roodt but rebounded into his net. This goal gave Bayern a strong lead early on in the match.

De Bruyne contributed another strike when he latched onto a through ball from Sane and converted it with precision. His goal put Bayern firmly in control of the game and ensured they would not be threatened further by Schalke.

Sane, making his first appearance since joining Bayern last season, added a third goal for his new team. He took advantage of a miscommunication between Schalke defenders and struck from distance, sending the ball past the keeper to give Bayern a comfortable 3-0 lead.

Julian Müller came on as a substitute in the 78th minute and made his debut for Bayern. However, his introduction did not result in any immediate impact on the game, and Bayern maintained their dominant position throughout the final stages.

The win over Schalke 04 maintained Bayern's unbeaten streak at home this season, now standing at 15 matches without losing. The club has now reached the halfway point of the season, having won nine games and drawn three, while conceding only one goal. With such a solid defensive performance and a lineup featuring some of the best players in Europe, Bayern Munich remains a formidable force in German football.

This result is particularly significant given that Bayern have already clinched the Bundesliga title, leaving them to focus solely on the UEFA Champions League and domestic cup competitions. The club's ability to maintain its dominance in both the league and杯 competitions demonstrates the depth and quality of their squad, which includes several key players like Müller, De Bruyne, and Sane.

Overall, the performance by Bayern Munich in this round of the Bundesliga demonstrated their continued dominance and resilience in the face of competition. Their clean sheet and strong performances across the board will likely help them secure their place in European football's elite clubs for years to come.
