In recent games, Portugal has displayed attractive attacking football, but the defense has, at times, been lacking. The recent friendly against South Korea exposed some gaps in the defensive line, especially in quick transitions from the opposition. To maximize their chances of success in the 2026 World Cup, it is imperative that coach Roberto Martínez considers specific tactical adjustments.

One of the most pressing issues is the organization of the defensive line. Portugal has been using a 4-3-3 formation, which, while providing strength in midfield and attack, can create spaces on the flanks when full-backs push forward. To address this, a shift to a 4-2-3-1 formation could provide additional coverage, allowing defensive midfielders to position themselves closer to the defensive line and offer support during counter-attacks.

Moreover, communication between the center-backs and full-backs needs improvement. Understanding and coordination are crucial, especially against teams that exploit the flanks. Clear instructions on when to press or drop back can help avoid situations of 2-on-1, which have become frequent in recent matches.

Another aspect to consider is the high press. Portugal has shown good offensive potential, but the high press often leaves the defense exposed. Training a system where the team quickly retreats after losing the ball, rather than maintaining pressure, may prove more effective. This not only protects the defense but also allows players to position themselves more strategically to regain possession.

Finally, introducing a defensive leader at the back might be what is needed to stabilize the defense. A player with experience and game-reading ability can be essential in organizing the defense and ensuring that everyone is on the same page. The presence of a player like Rúben Dias, who has already shown great potential, could be key in this aspect.

With these considerations in mind, Portugal will have a more solid defensive foundation that can withstand the intense pressure of the World Cup. The combination of a robust defense with creative attacking play may be the key to A Seleção das Quinas' success in the upcoming tournament.
