Nottingham Forest will decide during the international break whether to stick with Ange Postecoglou if their winless streak is extended at Newcastle on Sunday.
Thursday's home defeat by Midtjylland in the Europa League, in front of owner Evangelos Marinakis, saw the home crowd turn on Postecoglou after a sixth game without a victory for the Australian, who was appointed only on September 9.
Fans chanted 'You're getting sacked in the morning' and sang for former boss Nuno Espírito Santo - himself dismissed by Forest only last month and now at West Ham.
