In recent matches, Nacional has shown great dynamic play, but there are areas that need tactical adjustments to optimize performance. The 4-2-3-1 formation employed by the coach has its merits, allowing midfielders to create plays and attackers to pressure the opposing defense. However, the lack of defensive cohesion during transitions has been an evident weakness.

One of the main issues is the vulnerability on the flanks. While the full-backs are offensively minded, they often leave open spaces that opponents can exploit. To mitigate this, a shift to a 4-4-2 formation at certain moments in the game could provide a more solid defensive cover, especially against teams that play on the counter-attack.

Additionally, employing a more defensive midfielder, such as Eduardo Domínguez, could offer extra protection to the backline, allowing offensive midfielders to focus on creating goal opportunities. This change in defensive posture could be crucial in decisive games, especially against rivals like Peñarol.

In attack, Nacional has shown potential, but the lack of efficient finishing has been a concern. The inclusion of a target striker who can act as a pivot and create opportunities for the players behind could be a viable solution. Players like Juan Ignacio Ramírez need more support and passes in favorable positions, which could also be facilitated by a more compact midfield formation.

Finally, Nacional needs to adjust its possession approach. Instead of maintaining possession only in defense, the team should look to transition more quickly and verticalize their play. This would not only increase pressure on the opposition's defense but also allow attacking players to position themselves in dangerous areas more frequently.

In summary, while Nacional has a solid foundation, small tactical changes, such as formation shifts and style adaptation, could be the key to unlocking the team's true potential and ensuring a more consistent performance in the league.
