Chelsea boss Enzo Maresca admitted he had sympathy for Ange Postecoglou, who was sacked just minutes after Nottingham Forest's 3-0 defeat to Chelsea at the City Ground.
Postecoglou was relieved of his duties after just 39 days in charge. He had failed to win any of his eight games at the club.
Owner Evangelos Marinakis left his seat during the second half while Forest were 2-0 down and Postecoglou's sacking was confirmed 19 minutes after full-time.
An encouraging first half for Forest was quickly forgotten about within six minutes of the second period when Josh Acheampong headed home his first senior goal before Pedro Neto struck a free-kick beyond Matz Sels.
