Patrick Vieira has been sacked as manager of Ligue 1 side Nice after suffering a fifth defeat in a row.
The former Arsenal midfielder had been in charge of the French side for two and a half years but Thursday night's defeat to Bayer Leverkusen in the Europa League ended his reign.
Vieira led Nice to a fifth-place finish in the French top-flight last season but they are currently 11th in the league after 11 games.
The 3-2 loss to Leverkusen confirmed their exit from the competition and made it five consecutive defeats in all competitions.
The 44-year-old was under increasing pressure after Sunday's 3-1 defeat at home to Dijon, who had not won a game up until then.
