Nottingham Forest may consider replacing manager Ange Postecoglou if the team's performance doesn't improve. Postecoglou was appointed by owner Evangelos Marinakis after the sacking of Nuno Espirito Santo, but the team has struggled, with seven games without a win, including two draws and five losses.The pressure is mounting on Postecoglou, and the club is reportedly preparing for life without him. If a change is made, Forest's priority target is likely to be Fulham manager Marco Silva. Silva has experience working with Marinakis at Olympiacos, a club that is also owned by Marinakis.
