8 minute readMatías Navarro García is an Argentine coach, analyst and author of several books on football and video analysis. One of his greatest influences is fellow countryman, the charismatic Marcelo Bielsa, whose philosophy he attempts to explain in this article.
Note: This article has been translated into English from an original Spanish article submitted by Mr. Navarro.
It’s difficult to find someone in the world of football who is more studious and meticulous than Marcelo Bielsa. The man from Rosario, currently coaching at Leeds United, seeks to eliminate uncertainty in the game with a method of analysis which borders on the scientific.
"You know my team better than I do," said Pep Guardiola after Barcelona’s 3-0 victory over Bilbao in the 2012 Copa del Rey final, the Catalan showing admiration for the Argentinian’s video analysis work.
His analytical process, which has been developed and updated throughout his 30-year career, is based on three main principles: analysis of his own team, analysis of an opponent and a detailed understanding of football.
In the ongoing search to address the shortcomings of both individual players and the team at large, Bielsa uses video, not only to express opinions about players and their decision making, but also to teach movement based on references from elite players around the world and, also, from players in direct competition for a position.
But video analysis is not only aimed at individual players, it is key in the evaluation of entire clubs. Bielsa believes that when accepting a new job, he must start at the beginning of season, so as not to inherit any negativity and, before starting, he must perform a meticulous evaluation of what he has to work with including:
The analysis process begins with two complete watch-throughs of every competitive and friendly match his new club played during the previous season, which takes four hours per match. From there he:
This work is replicated for footballers on loan to other clubs and, also, with those who played for their national teams.
Although there are companies that record statistics, he prefers his technical team to collect this data, guided by his parameters and definitions of the game, for which video analysis tools help remarkably.
During his first season at Leeds, Bielsa made headlines for sending a spy to a Derby County training session, an act which was denounced by the club and condemned by the press and public.
Because of this, the coach explained that it was not necessary to sneak into training sessions in order to understand an opponent. He opened the doors and gave details about his analysis methodology.
To get a detailed view of an opponent he, once again, watches each of their games from both the previous season and the current season up to their meeting with Leeds twice, after which he creates:
An example of Mr. Bielsa's tactical sheets for a team
An example of Mr. Bielsa's tactical sheets for an individual player
An example of a list of events for a team
As detailed by Bielsa himself, he brings together approximately 40 minutes of attacking and defensive plays for each team: "When you watch all this material, you can easily find offensive plays and defensive weaknesses."
Logically, this first analysis is streamlined before being shown to the players whose concentration does not exceed 15 minutes. In the end they are shown an 8-minute video of offensive plays and another 8 minutes of defensive plays.
When not leading a team, Bielsa does not rest on his laurels. He busies himself creating work groups with other coaches in order to understand the dynamics and evolution of football. The criteria and parameters we looked at in the Analysis of Own Team phase is established at this point, when there is plenty time watch and analyse.
If he states, for example, that there are 11 ways to score, 10 base tactical schemes (which may later be varied slightly) or 5 ways to miss, none of these numbers are random and, in fact, each is supported by detailed analysis of the game.
One of these renowned groups was formed for the 2006 World Cup, a period between his resignation from the Argentinian National Team (2004) and his arrival in Chile (2007). Among others, Eduardo Berizzo, Claudio Vivas, Javier Torrente, Pablo Quiroga (his current right-hand man) and Ricardo Lunari all participated in this work.
The latter detailed some of the key points in analysis taught to him by Bielsa: “He showed me how to analyse video, how to stop and counter rival teams. He had me draw out the standing of each team and how duels could be established in every part of the field”.
Within this "forensic work", as Lunari himself defines it, he details two reports that he was assigned:
As we can see, video analysis is crucial for Bielsa in his daily work. To get to know his players in detail, to analyse opponents or to thoroughly understand the continually changing dynamics of football. Something which demands constant professional development in each and every member of his coaching staff.
