Remember that Nuno Espirito took over the club when they were 17th in the Premier League. Nottingham Forest made it to the top four previous season but dropped back due to some losses at the end of the season. There was a rumour that the club's owner fired Nuno in order to bring in Ange Postecoglou, who was fired by Tottenham after winning the Europa League.
Yes, you're right. Ange Postecoglou has been appointed as the new coach of Nottm Forest since 09.09.2025, and this contract will last for 2 years until June 2027. The appointment of Ange Postecoglou as their new head coach, according to Evangelos Marinakis, is because they consider Ange as a coach who has been tested and has a record of winning trophies. He is expected to be able to make Nottm Forest more consistent so that they can become much stronger and win more.
