Lille have appointed a four-man coaching team to take provisional charge after Marcelo Bielsa's dismissal.
The Ligue 1 club said Fernando Da Cruz, Joao Sacramento, Benoit Delaval and Franck Mantaux would take charge until further notice.
Earlier this week, Lille announced that Bielsa had been suspended "as part of a procedure started by the club" following the 3-0 defeat at Amiens.
The club are 19th in the table and on Saturday travel to Montpellier, who have the best defence in the league.
Bielsa joined Lille this season but failed to revive their fortunes after they had finished in a disappointing 11th place last season.
