Marcelo Bielsa has signed a two-year contract to take over as Lille head coach from the start of next season, the Ligue 1 club have confirmed.
The former Argentina boss will return to the French top flight having guided Marseille to a fourth-place finish in 2014-15.
Only champions Paris Saint-Germain outscored a swashbuckling Marseille that season but Bielsa quit after losing the opening game of the following campaign to Caen.
There was further evidence of the 61-year-old's infamous volatility when he was named Lazio boss in July last year, only to resign two days later amid claims the Serie A side had made no progress towards his requested transfer targets.
Last week, Lille appointed Franck Passi - a former assistant to Bielsa at Marseille - as interim head coach until the end of this season.
Passi replaced Patrick Collot, who took charge after Frederic Antonetti was sacked in November.
Lille won 1-0 at Caen on Saturday, with Anwar El Ghazi scoring the winner shortly after Adama Soumaoro received a second-half red card, and sit four points above the relegation zone in 14th.
