Marcelo Bielsa has been appointed as Leeds' new head coach, the club have confirmed.
The Argentinian has signed a two-year deal to succeed Paul Heckingbottom at Elland Road, with an option for a third season.
Bielsa said: "I am delighted to accept the role of head coach at Leeds United. It has always been my ambition to work in England."
Bielsa, 62, has previously managed both his national team and neighbouring Chile and enjoyed his greatest club success when he led Athletic Bilbao to the 2012 Europa League final.
His career since then has been eventful with Bielsa quitting Marseille after the opening game of the 2015-16 Ligue 1 season, walking out on Lazio after just two days in charge and being sacked by Lille last season after a club suspension.
Leeds chairman Andrea Radrizzani said: "I am thrilled to welcome Marcelo and his staff to Leeds United.
"Marcelo has a wealth of experience and he will use that to create a new culture and a winning mentality at our football club."
Bielsa added: "When a club with Leeds United's history made me an offer, it was impossible to turn down.
"I am excited for the challenge ahead and I look forward to collaborating with Victor (Orta, director of football), Andrea and Angus (Kinnear, managing director) as we work hard to achieve great things at this football club."
