When FC Chur appointed Iñaki Arriola, the project was initially framed in familiar terms: a structurally compact, transition-oriented side built on clear positional references and a strong ideological backbone. Over time, however, the evolution of the team has become more nuanced than that original label suggests. What is emerging in Chur is not a departure from identity, but a refinement of how that identity is applied. The club’s assistant manager, Xavi Tamarit, has become a key figure in this shift – working closely with the coaching staff and performance analysts to translate opponent-specific data into actionable tactical adjustments without compromising the team’s core principles.

Rather than moving towards a purely reactive model, Chur’s development reflects a more sophisticated balance: fixed structural ideas in possession and out of possession, combined with a growing sensitivity to opponent behaviour. The result is a framework where control is no longer defined solely by possession, but by decision-making – knowing when to circulate, when to accelerate, and when to bypass pressure entirely.

In this interview, Tamarit discusses how data integration, coaching alignment, and in-game adaptability are reshaping Chur’s tactical model from within, while preserving the identity that first defined the project.

Spielverlagerung: From the outside, FC Chur still look like a very clear ideology-driven team. But there’s a sense now that something has evolved – particularly in how you approach different opponents. Is that accurate?

Tamarit: Yes, but it is important not to confuse evolution with change of identity. The positional structure, the rest defence, the compactness – these remain constant. That is the foundation built by the head coach, Iñaki Arriola. What has evolved is our interpretation of the opponent. Before, we imposed our structure in a more fixed way. Now, we still impose the structure – but within that, we are more flexible in how we progress the ball.

Spielverlagerung: When you say “interpretation,” what does that actually look like in practice?

Tamarit: It’s mainly about identifying the opponent’s out-of-possession behaviour – specifically their pressing height, intensity, and how many players they commit forward. From there, we define whether the game demands that we play through the press or bypass it. That single decision influences tempo, directness, even width.

Spielverlagerung: So you’re essentially toggling between different build-up strategies depending on the opponent?

Tamarit: Yes, but always within a controlled framework. For example, if the opponent presses high but only leaves one or two players forward, we are comfortable building short. We can attract pressure, create superiorities, and progress through them. But if they press high and leave three or four players high, the risk profile changes completely. In those moments, insisting on short build-up is not intelligent. We may increase tempo, go more direct, and attack the space behind.

Spielverlagerung: When you say “go more direct,” do you mean abandoning your positional principles, or is this still structured?

Tamarit: No, never abandoning. “Direct” for us is still targeted. It is not random long balls. It is about accessing space quickly when the opponent has stretched the pitch vertically. Our rest defence remains intact. Our occupation of zones remains logical. The difference is simply the speed and length of the action.

Spielverlagerung: This sounds like a fairly significant shift towards opponent-adaptive football. How much of this is driven by your data department?

Tamarit: A lot, but in a very collaborative way. Our analysts don’t give us instructions – they give us clarity. They show us patterns: how teams press, where they leave space, how stable they are in transition. For example, they might highlight that a team’s weak-side winger does not recover quickly. From this, we can plan to circulate the ball and attack that space.

Spielverlagerung: So the data is not prescribing actions, but shaping your perception of the game?

Tamarit: Exactly. It allows us to make better decisions faster. Instead of relying only on intuition, we have objective references including the number of players committed in the press, the distance between units and the speed of defensive transitions. This helps us decide, for example, whether to increase tempo or remain patient.

Spielverlagerung: Has this changed how Iñaki Arriola behaves on the touchline? Is he more reactive during matches now?

Tamarit: I would say he is more aware. Before, the idea of control was strongly linked to maintaining our rhythm – short passing, positional dominance. Now, he recognises that control can also mean accelerating the game when the opponent creates the conditions for it.

So yes, during matches we are more willing to adjust tempo, change passing directness or shift the focus of play: but always without losing our structure.

Spielverlagerung: Can you give a concrete in-game example of that?

Tamarit: Yes. Let’s say we prepare for a high press with few players left forward – we plan to play through it. But after 20 minutes, we see that the opponent is committing more players forward than expected. Suddenly, the spaces behind are larger, but also the risk in build-up increases.

In that moment, we may switch and increase tempo, play more directly or use the goalkeeper to access longer passes This is not a full tactical change – it is an adjustment of behaviour.

Spielverlagerung: You mentioned rest defence several times. Has that been affected at all by these adaptations?

Tamarit: No, this is one of the pillars. Regardless of the opponent or the game state, we maintain a stable rest defence – usually with at least three players behind the ball and a central presence. This allows us to attack with aggression while remaining protected against transitions.

Spielverlagerung: So even when you increase tempo or play more directly, that structure is preserved?

Tamarit: Always. If you lose that, you lose your ability to sustain pressure and control transitions. Then you are no longer adapting – you are reacting without stability.

Spielverlagerung: Finally, if you had to summarise the evolution of this team in one idea, what would it be?

Tamarit: We have not changed what we believe in. We have improved how we apply it. The data has helped us understand when to be patient and when to be vertical. Before, maybe we leaned too much in one direction. Now, we have a better balance. 

Spielverlagerung: So the identity remains, but the execution is more flexible?

Tamarit: Yes. The structure is fixed. The principles are fixed. But within that, we now have more solutions. And in modern football, having more solutions – without losing your identity – is the real advantage.
