Luis Maria Bonini – a long time member of Marcelo Bielsa’s coaching staff including assisting him at Athletic Bilbao – has passed away.
The Chilean was a fitness coach alongside the famed manager during his stints with Atlas de Guadalajara, Club America, Velez Sarsfield, RCD Espanyol, Argentina, Chile and Athletic Club Bilbao.
Bielsa has been suspended by Ligue 1 club Lille – for whom he is currently managing – reportedly for visiting his former assistant recently whilst he was battling stomach cancer.
Bielsa — nicknamed El Loco (The Mad One) — is well-known for his flamboyant style of management and led Athletic to the 2012 Europa League final.
Bonini, 67, was working with Mexican club Morelia before taking time off for his illness.
