French Ligue 1 strugglers Brest have handed the reins of the first team to sporting director Corentin Martins for the remainder of the season, president Michel Guyot told AFP on Wednesday.
Martins steps into the void left by Landry Chavin, who was sacked on Tuesday after a run of one win in 10 games left the Brittany side in the relegation zone.
Martins, a former French international who played for Brest between 1988 and 1991, has already taken charge on an interim basis on two previous occasions, including last season.
He took over for the final five games of 2011-12, keeping Brest in Ligue 1 after Alex Dupont was sacked.
Chauvin became the fourth managerial casualty of the season in Ligue 1, with Evian, Ajaccio and Nancy also having parted company with their coaches since the campaign began.
