Unai Emery was sacked as Arsenal manager Friday after less than two years in charge and with the club without a win in seven games, their worst run since 1992.
The 48-year-old Spaniard was fired following the 2-1 home defeat to Eintracht Frankfurt in Thursday's Europa League match.
His assistant Freddie Ljungberg takes over as interim manager during the search for a permanent replacement.
Arsenal fans had demanded "decisive action" from directors with the club's present run of five draws and two defeats this season just one match off equalling George Graham's run of eight without a win in 1992.
