Marcelo Bielsa is set to become Athletic Bilbao coach after former captain Josu Urrutia was elected as the club's new president.
The Basque side announced on Friday that Urrutia won 54.36 per cent of the vote in Tuesday's election to oust the incumbent, Fernando Garcia Macua.
Urrutia had announced days earlier that an agreement had been reached for Bielsa to be handed the reins of the first team if he won the election.
The former Argentina and Chile coach is expected to fly to Spain on Sunday and start his new job on Monday.
The 55-year-old Argentine will replace Joaquin Caparros, who was Macua's choice to remain in charge.
The new president described Bielsa as "one of the top seven or eight coaches in the world", insisting that "his virtues and Athletic's needs fit together like a hand in a glove".
Bielsa has been without a job since stepping down as Chile coach in February, although he did reject advances from Italian giants Inter Milan earlier in the summer.
His Chile side earned plaudits for their attractive playing style en route to the last 16 at last year's World Cup in South Africa.
It will be his second spell as a coach in Spain after a brief spell with Espanyol in 1998, shortly before he started a six-year spell as Argentina coach.
Athletic finished sixth in La Liga last term, qualifying for next season's Europa League.
