Marcelo Bielsa: The Coaching Tree That Changed Football

Marcelo Bielsa has won fewer major trophies than almost any coach of his fame, yet no living manager has shaped more managers. Pep Guardiola calls him the best in the world; Mauricio Pochettino, Diego Simeone and Jorge Sampaoli built careers on his ideas. The coaching tree of El Loco, the Crazy One from Rosario, is the strangest in football: a forest grown by a man whose own harvest keeps disappointing the trophy counters.

The paradox dissolves when you separate winning from teaching. Bielsa's teams are laboratories of intensity, and the assistants, players and rivals who pass through them leave with a complete education in how football can be organised.

The method: obsession as a system

Bielsa's football is built on a few convictions held with religious force. His teams press man-to-man all over the pitch, attack with verticality the moment the ball is won, and train at an intensity that mirrors matchday, because he believes performance is mostly preparation. The famous 3-3-1-3 formation is just the container; the content is the demand that every player runs, presses and passes as if the match depends on each action, because in his model it does.

The work ethic is legendary and documented: hundreds of match videos analysed per opponent, training sessions rebuilt from frame-by-frame study, and a personal austerity, living at the training ground, that disciples either find inspiring or unsustainable. At Athletic Bilbao his 2011-12 side played some of the most admired football in Europe and finished with two lost finals, which is the Bielsa story in one sentence.

The disciples, mapped

The tree's branches reach every corner of elite football.

• Pep Guardiola, who travelled to Rosario in 2006 for a long conversation with Bielsa before starting his coaching career, and still cites it as a founding lesson.
• Mauricio Pochettino, whom Bielsa discovered as a teenage defender at Newell's Old Boys and later coached at Espanyol and Argentina, now a top-flight manager for two decades.
• Diego Simeone, Bielsa's midfielder with Argentina, whose Atlético Madrid married Bielsa's intensity to a defensive pragmatism the teacher never embraced.
• Jorge Sampaoli, who took Chile to the 2015 Copa América title playing the most overtly Bielsa-inspired football since Bielsa's own Chile.
• Gerardo Martino and Eduardo Berizzo, Newell's alumni who carried the method to Barcelona, Paraguay, Sevilla and beyond.

Leeds: the tree's most recent classroom

Bielsa's Leeds United spell, from 2018 to 2022, introduced his coaching to English football at scale. He took a mid-table Championship club to the league title in 2020, ending the club's sixteen-year exile from the Premier League, and the promoted side's fearless man-to-man pressing earned a ninth-place finish and admirers across the league. The burnout that followed, the squad's physical collapse in his final season, is equally instructive: the method's intensity is both its genius and its expiry date.

With Uruguay, whom he took over in 2023, the pattern repeated again: a historic 2-0 win in Buenos Aires against Argentina, a Copa América semi-final in 2024, and the same debates about sustainability that have followed him since Newell's.

Why the tree keeps growing

Bielsa's influence survives his trophy count because his ideas are teachable. Pressing schemes, training periodisation, video analysis and the 3-3-1-3 can all be copied; charisma cannot. His disciples took the system and left the mystique, which is why the tree flourishes in clubs the old man never visited.

The South American chapter of the tree is its own story. Bielsa's years with Argentina and Chile turned him into a reference point for an entire generation of the continent's coaches, and his insistence on video analysis and physical preparation professionalised national-team setups that had run on talent and improvisation. Coaches from Uruguay to Colombia still structure their weeks on templates that descend from his, and the 2024 Copa América, with his Uruguay pressing opponents into errors, showed the method remains competitive at the highest level.

Football measures coaches in medals. Bielsa measures himself in players taught and ideas planted, and by that accounting he is the richest man in the dugout.
