Carlos Carvalhal left Sheffield Wednesday on December 24, 2017 after two and a half years in charge at Hillsborough.
The Portuguese, who guided the Owls to the play-offs in his first two seasons at the helm, departed the Sky Bet Championship club by mutual consent on the back of a seven-game winless run.
His exit came just hours after chairman Dejphon Chansiri released a statement of support for his head coach after fans chanted for his dismissal in the wake of a 2-1 home defeat to Middlesbrough a day earlier.
Carvalhal said on Wednesday’s official website: “The chairman and myself talked after the game and we believed this was the correct timing to make this decision.
“Of course, I am very sad at this moment because I have enjoyed my two seasons and a half so much with Sheffield Wednesday.
“We had two fantastic seasons and two play-offs in a row but unfortunately we have not managed to replicate these positions this season.
“Now is the time to focus on the wonderful experiences I have enjoyed at Sheffield Wednesday and the friends I have made.”
Carvalhal’s exit came as something of a surprise given how quickly it followed an apparent vote of confidence from Chansiri.
