Nottingham Forest boss Ange Postecoglou is facing a tough time at the City Ground, with the team currently on a nine-game winless streak.
Despite the recent 2-0 defeat at Newcastle, which left the club 17th in the Premier League table, Postecoglou is not considered the biggest mistake made by the club.
Postecoglou is already at risk of the sack at Nottingham Forest after a disastrous spell since replacing Nuno Espirito Santo.
The pressure on Postecoglou will only intensify as Chelsea travel to the City Ground after the international break.
