Postecoglou was relieved of his duties just 39 days after taking over from Nuno Espirito Santo after Forest's 3-0 defeat to Chelsea in the Premier League at the City Ground. 

Indeed, Postecoglou at Forest is the first manager to see his team score only one goal in his first five Premier League matches in charge since Dyche at Burnley in 2014.

The Tricky Trees also conceded 11 set-piece goals during Postecoglou's short tenure in all competitions, over twice as many as any other top-flight club in that time. 

Forest hierarchy will be hoping that the appointment of Dyche will bring a familiarity back into their style of play that heralded European football under Nuno in 2024-2025. 

Dyche has been out of work since January after he was dismissed by Everton after a poor run of results that left it one point above the Premier League relegation zone. 

Across his two-year stint on Merseyside, Dyche's team conceded 105 goals, the fifth-fewest among sides who spent the entirety of his tenure in the top-flight.

But over the same period, his team managed to score just 74 times. Only the seven promoted teams in that timeframe netted fewer. 

Dyche's first game in charge will be for Forest's Europa League clash with Porto at the City Ground on Friday, with Bournemouth in the Premier League after three days later.
