Steve Cooper has been sacked by Nottingham Forest with Nuno Espirito Santo set to arrive as his replacement.
Cooper guided the club to Premier League promotion in 2022, while also ensuring they beat the drop last term.
Forest have struggled in the top flight so far this season, however, winning just three of their 17 matches.
After a 2-0 defeat to Tottenham over the weekend, they sit just five points above Luton Town in the relegation zone.

Cooper often had the backing of Forest fans during his time at the City Ground.
Yet he's now paid the price for the club's struggles this season, with the Premier League side opting to relieve him of his duties.
The Daily Mail say owner Evangelos Marinakis has been left 'unsatisfied' by the club's displays this season.
Cooper was close to being removed from his post earlier this month after a 5-0 defeat to Fulham on December 6.
But Forest have now opted to wield the axe now.
Nuno is now expected to take over at the City Ground.
The Portuguese has managed in the Premier League before, having previously enjoyed successful stint in charge of Wolves.
Nuno was also briefly manager of Tottenham, though lasted just 17 matches before being sacked.
However, the 49-year-old isn't the only name in the frame when it comes to potentially taking over.
Marinakis is said to be considering hiring Oliver Glasner, who is out of work following his departure from Eintracht Frankfurt at the end of last season.
Another boss admired by the Forest owner is Julen Lopetegui.
The Spaniard, who has also been linked with Manchester United, left Wolves before the start of the season.
And Fulham's Marco Silva can't be entirely ruled out, either.
Silva previously worked under Marinakis at Olympiacos and has been widely praised for the work he's done in west London over the past few years.
Cooper admitted earlier this month that he'd spoken to the board about his future.

"I spoke to Miltos (Marinakis) on the phone about the game, and Ross Wilson (chief football officer)," he said prior to a meeting with Wolves.
"We just spoke about the game.
"It was a good conversation, as it always is. We all got on the bus and back on the laptops and carried on.
"But I've not heard from anyone else. We were back in early and carrying on with our day's work.
"I won't walk out of here fearing for my job, that's a terrible thing to think."
