In recent friendlies, the Canarinho squad has shown a more dynamic and offensive style of play, but some weaknesses are still evident. The formation used, predominantly a 4-2-3-1, allows Brazil to maintain ball possession and explore the flanks, but the lack of adequate defensive balance has raised concerns. The team needs to find a middle ground between creativity in attack and solidity in defense.

One of the main points to be adjusted is the positioning of the midfielders. While Casemiro and Bruno Guimarães provide excellent protection to the defense, the freedom of movement of full-backs like Alex Sandro and Danilo can create defensive gaps during quick transitions from the opponent. A more cautious approach, with one midfielder dropping back to form a three-man defense during opponent attacks, could mitigate these risks.

Moreover, the integration of younger players could bring freshness to the tactical system. Vinícius Júnior has been outstanding, but utilizing players like Rayan and João Pedro at strategic moments could offer new dynamics to the attack. The Canarinho squad should explore more triangulations and deep plays, especially against teams that tend to sit back defensively.

Another consideration would be varying the formation in specific matches. Instead of sticking with the 4-2-3-1 in every game, an occasional shift to a 4-3-3 or even a 3-5-2 could catch opponents off guard and create new attacking opportunities. This tactical flexibility is vital, especially against teams that are well-acquainted with traditional Brazilian style.

Lastly, the psychological aspect and the players' confidence are crucial. The Canarinho squad must work on cultivating a resilient mindset, capable of adapting in adverse situations. The use of intensive training and game simulations can help strengthen this mentality, preparing the team for the challenges that lie ahead in the 2026 World Cup.
