Sean Dyche is in advanced talks with Nottingham Forest about the prospect of becoming their new head coach - but other candidates have not yet been ruled out.
Former Manchester City boss Roberto Mancini has held positive talks about replacing Ange Postecoglou, who was brutally sacked 18 minutes after Saturday's 3-0 defeat to Chelsea.
Forest bosses have also shown interest in Italian coach Luciano Spalletti, who was sounded out about the role but, according to Sky in Italy, he is no longer in contention.
Ex-Olympiakos head coach Pedro Martins, the Portuguese currently working in Qatar, was considered, but will not be taking over at Forest.

While Mancini is not yet out of the running, Sky Sports News has been told that Dyche is very much the front-runner, and could be appointed quickly if owner Evangelos Marinakis finally decides he is the right man to replace Postecoglou.
The Australian, who failed to win any of his eight games in charge at Forest, was sacked within 18 minutes of the defeat to Chelsea at the City Ground on Saturday lunchtime.
The decision over finding a replacement for Postecoglou lies entirely with Marinakis, who is looking for his third head coach of the season at Forest.

ANGE SACKED
Sky Sports' Anton Toloui reports from the City Ground on what happened surrounding Ange Postecoglou's sacking from Nottingham Forest.
He knows this next managerial appointment is key in trying to produce some stability and belief in the dressing room and amongst the supporter base after a damaging period for the club.
In that regard, Forest's hierarchy currently believe Dyche is the best man to steady the ship, organise and motivate the players, and crucially keep the club in the Premier League despite having ambitions of finishing further up the table.
Another key demand from the owner is for whoever takes over to maximise the significant investment that was made in the playing squad in the summer.
Forest spent more than £180m in the transfer window, and £130m of that talent wasn't in the matchday squad against Chelsea. This was another area of dispute between the owner and Postecoglu, Sky Sports News has been told.
Despite the importance of the appointment, Forest's bosses are keen to move quickly, with the Europa League game against Porto to come on Thursday.
