In the spring of 2008, Barcelona was in a performance crisis and the board was looking for a radical change. José Mourinho's unexpected departure from Stamford Bridge and his reputation as a successful manager at Porto and Chelsea made him an attractive option for the Catalan club, who feared a second trophyless season. Mourinho's proposal materialized in a meeting in Lisbon, where the former Setúbal coach presented a 27-page dossier on how he would lead Barça.
The document, kept by then sporting vice president Marc Ingla, contained a detailed plan that included the implementation of a 4-3-3, intensive use of the ball and a rigorous physical approach. It also outlined an exhaustive analysis of the squad, questioning the continuity of players like Ronaldinho and suggesting the permanence of Eto'o and Deco. In addition, possible additions to the coaching staff were being considered, such as Luis Enrique, Chapi Ferrer or Sergi Barjuan, with whom Mourinho had worked in the past.
Despite the clarity of the plan, the relationship with the media and the lack of consensus within the board limited the viability of the proposal. The board, influenced by the advice of Johan Cruyff, opted for Pep Guardiola, who had begun coaching the reserve team. The decision was made in a context of friction between Mourinho and the media, especially after the clashes with Barça in the Champions League qualifiers.
The result was the arrival of Guardiola, who, together with the explosion of talent of Lionel Messi, led Barcelona to become one of the most successful teams in history. Meanwhile, Mourinho remained an outspoken critic of the club, establishing himself as one of its biggest public enemies. The story of Mourinho's flash drive illustrates how a well-structured plan can be overshadowed by internal politics and leadership decisions within a world-class club.
