Nottingham Forest dismissed head coach Ange Postecoglou around 20 minutes after Saturday’s 3-0 home defeat to Chelsea ended.
Postecoglou lasted just 39 days at the helm, losing six and drawing twice during his brief spell in charge.
“Nottingham Forest Football Club can confirm that after a series of disappointing results and performances, Ange Postecoglou has been relieved of his duties as head coach with immediate effect,” the club statement read.
