Paco Seirul·lo’s ‘Entrenamiento estructurado’: a guide for youth training
As a parent, coach or young footballer you want a training method that is not only technically strong, but also stimulates the child's development as a complete athlete. Paco Seirul·lo, the Spanish architect behind the famous FC Barcelona‑methodology since 1978, has formulated his own approach: Entrenamiento estructurado. In this article we dive deep into his philosophy, the building blocks he uses, and how you can apply them in practice. Whether you are guiding a 7‑year‑old talent or coaching a U13 team, Seirul·lo's insights provide a clear framework for structured growth.
What is “Entrenamiento estructurado”?
Seirul·lo describes training as an organized microciclo in which every training session, every drill and even every rest period gets a specific place within a larger whole. The premise is that the player is seen as a complex system: technical, tactical, physical and mental aspects are inseparably linked. Instead of planning isolated drills, each component is chosen to serve a purpose within the broader cycle. A microciclo might, for example, consist of a phase of ball dominance, followed by a period with juego de posición, and then a concluding round of rondos to strengthen decision‑making. The result is a training that combines consistency and variation, continuously challenging the player while following a clear development path.
The publication "Entrenamiento en deportes de equipo: el entrenamiento estructurado en el FCB" (2019) explains this concept step by step. Seirul·lo emphasizes that a well‑structured microciclo not only raises the quality of the drill, but also the learnability of tactical principles. By following a repeating pattern, the player instinctively learns which choices the game demands, without each decision having to be explained anew each time. For parents and coaches this means spending less time constantly repeating basic rules and being able to focus more on refining game insight.
Ball dominance, juego de posición and rondos: the building blocks of the Spanish youth philosophy
In Spain the emphasis from the very youngest age is on ball dominance. This means that children learn early to control the ball, pass under pressure and move with the ball close to their feet. The idea is that a player who is comfortable with the ball can make decisions faster and becomes less dependent on physical strength. Seirul·lo has integrated this philosophy into his structured approach by placing ball dominance as the first phase of every microciclo.
Next comes the juego de posición (game formation) – a system in which players constantly optimise their position relative to each other. In practice this looks like small game formats where players are encouraged to create, recognise and exploit space. This form of play is introduced already in 7v7 formats, allowing children at a young age to learn how to position themselves relative to teammates and opponents. The result is a game insight that later transitions seamlessly to larger formations.
Rondos, a classic Spanish drill in which a group of players must keep possession of the ball against one or two defenders, form the third pillar. Rondos train both technical speed and tactical insight: players must constantly adjust their position, choose the right pass and anticipate the defender's movement. In a structured microciclo a rondos session is often used as a bridge between ball dominance and more complex game formats, because it forces players to apply their previously learned skills under time pressure.
The transition to 11‑against‑11 and the introduction of offside around U13
A hallmark of the Spanish development philosophy – and a specific focus in Seirul·lo’s method – is the relatively early transition to 11v11 around the U13 age. While some countries switch later, Spain lets children from U13 onward experience the full pitch size, the complexity of a full formation and the dynamics of a full match. This early step is not arbitrary; it is based on the belief that players who are accustomed to a wide playing area at a young age develop spatial understanding more quickly.
With the introduction of 11v11 the offside also comes into play. In the Spanish approach offside is usually introduced around U13, because by that time players have sufficient experience with juego de posición and the positional relationships between teammates. The concept of offside is crucial for learning timing, movement without the ball and creating space – all elements that have already been practiced in earlier phases of the microciclo, but now in a more complex context.
Another important aspect is the Basque territorial identity, a concept especially emphasized in the development of clubs like Athletic Bilbao. It revolves around a strong sense of territory and group cohesion. Although Seirul·lo himself works mainly with Barcelona, he weaves into his structured approach the idea that players should develop a ‘territorial’ bond with their team. This means children learn to defend their own playing space, but also to recognise when they need to create space for their teammates. It strengthens both individual responsibility and collective awareness, and fits perfectly with the transition to full 11‑against‑11 games.
Practical tips for parents and coaches: structured training in practice
1. Plan a clear microciclo – Start with an overview of the week: two to three sessions with ball dominance, one session juego de posición and one round of rondos. Keep the order consistent so players know what to expect.
2. Use small game formats – For the ball dominance phase you can use 5‑against‑5 on a small pitch. Have players pass with one‑or‑two‑touch and stay under pressure. Focus on accuracy, not distance.
3. Integrate ‘position questions’ – During juego de posición ask questions such as: “Where is your best passing option?” or “How can you shield your opponent?” Let players try out their answers and briefly discuss the outcomes.
4. Rondos as a transition drill – Run rondos with three defenders against five attackers. Change the defenders' positions every three minutes to force players to reconsider their passing options.
5. Introduce offside in game formats – From U13 you can play a 7v7 match applying a simple offside rule. Let players first experience offside on a limited number of occasions, so they learn to feel the impact of timing.
6. Focus on territorial awareness – Use drills where each team must defend a ‘zone’. For example, split the pitch into three zones and have each team try to maintain their zone while moving the ball.
7. Reflection and feedback – End each session with a short round where players name one thing they have learned and one challenge for the next training. This reinforces the learning objectives of the microciclo and makes progress measurable.
8. Involve parents – Explain that the structure is not only for the coach, but also for the home environment. Encourage parents to do simple ball dominance exercises at home, such as one‑touch passing against a wall, so that the training continues off the pitch.
Conclusion
Paco Seirul·lo’s Entrenamiento estructurado provides a clear framework in which ball dominance, juego de posición and rondos reinforce each other and lead to a smooth transition to full 11‑against‑11 games around U13. By approaching the player as a complex system and integrating each training session into a thoughtful microciclo, an environment is created where young players not only acquire technical skills, but also develop tactical insight, territorial awareness and mental resilience. For parents and coaches this means that a structured approach not only raises the quality of training, but also increases the child’s engagement and enjoyment. With the practical tips in this article you can start immediately applying Seirul·lo’s principles – so every training becomes a step closer to a complete, confident footballer.
