Postecoglou’s departure means Forest are searching for their third manager already this season, having sacked Nuno Espirito Santo just three matches into the campaign.

On Forest’s radar is Fulham head coach Marco Silva, with sources indicating the Portuguese is the preferred option of several internal figures at the City Ground.

Silva, who worked under owner Evangelos Marinakis at Olympiacos, has cemented Fulham’s position in the Premier League by adopting the sort of football Forest believe can help stabilise them following their poor start to the season.

But Silva is under contract at Craven Cottage, with sources informing BBC Sport the 48-year-old has a “significant” release clause in his contract.

Having just paid off Nuno and with Postecoglou due compensation, there would be an obvious reluctance to fork out a further large sum to appoint Silva, particularly given he will be available for free when his contract expires at the end of the season.

Given the difficulties attached to attracting Silva, it is understood Forest have studied the merits and, more pertinently, potential costs of alternatives.

Sources have told BBC Sport that the prospect of reappointing Steve Cooper, who led Forest back to the top flight in 2022 before being sacked and replaced by Nuno in December 2023, has been considered.

But Cooper was recently appointed head coach of Danish club Brondby.

Another option explored, as reported by BBC Sport last week, is the appointment of Sean Dyche.

The attraction of the former Burnley and Everton head coach is clear – he has a proven track record in keeping teams in the Premier League, and his tactical approach is akin to the style Forest are targeting.

Dyche, who left Everton in January, also lives close to Nottingham and is available without the need to pay a release clause.
