The Spanish national team has undergone a tactical shift in recent years, with the introduction of a 5-defender formation that has been hailed as one of the most effective defensive systems in world football.

In the past, the Spanish team was known for its attacking flair and creativity, but this approach often came at the expense of defensive stability. However, under new coach Julen Lopetegui, the team has shifted towards a more solid defensive system, with the introduction of a 5-defender formation.

This formation is designed to provide a high wall of defense, with each player responsible for their own area of the pitch. This means that there are fewer players on the field who can be targeted by opposing attackers, giving the team a greater sense of security and stability.

One of the key benefits of the 5-defender formation is that it allows the team to play out from the back, which can be particularly effective against opponents who tend to play on the counter-attack. By pressing high up the pitch, the team can disrupt the opposition's rhythm and create space for themselves, while also providing a strong defensive presence.

Another advantage of the 5-defender formation is that it allows for greater flexibility in terms of substitutions and rotations. With only five defenders on the field at any given time, there are always options available to make changes to the team's shape and structure, depending on the opponent and the match situation.

Overall, the switch to the 5-defender formation has been a success for Spain, with the team now enjoying a greater sense of stability and confidence on the pitch. Under Lopetegui's leadership, the team has won several important matches and tournaments, including the World Cup and Euro 2016, demonstrating the effectiveness of this defensive system.
