Carlos Carvalhal has left his position as Sheffield Wednesday head coach by mutual consent, the Sky Bet Championship club have confirmed.
The Portuguese, who guided the Owls to the play-offs in his first two seasons at Hillsborough, leaves the club on the back of a seven-game winless run.
His exit comes just hours after chairman Dejphon Chansiri released a statement of support for his manager after fans chanted for his dismissal in the wake of Saturday’s 2-1 home defeat to Middlesbrough.
Chansiri has now said in another statement: “Both parties believe the time is right to go our separate ways.”
The Thai businessman, who appointed Carvalhal in 2015, added: “I would like to offer my sincere thanks to Carlos for the time, effort and commitment he has given Sheffield Wednesday over the last two and a half years.
“I maintain a huge amount of respect for Carlos as a coach and as a person and he will always be welcome at Hillsborough.
“I wish him every success in the future.”
Lee Bullen will take charge of Wednesday’s game at Nottingham Forest on Boxing Day and could be in charge for the entire festive period, taking in matches with Brentford and Burton.
Carvalhal was a left-field appointment in the summer of 2015 as the 52-year-old was an unknown coach who had been out of the game for three years.
But he proved an astute selection as in his first season at the helm he took the Owls to within 90 minutes of a first Premier League return in 16 years, before they suffered a play-off final defeat to Hull.
He delivered a second successive play-off campaign last season, but that one ended in a semi-final defeat to Huddersfield.
Despite some heavy investment, including the £10millioin signing of Jordan Rhodes, the Portuguese has been unable to repeat that success this term and a seventh game without a win left the Owls in 15th and nearer the relegation zone than the play-offs.
That saw a lot of fans increasingly turn against Carvalhal, culminating in chants for his removal after the defeat to Boro.
His exit still comes as something of a surprise, given how quickly it followed an apparent vote of confidence from Chansiri.
Chansiri posted a lengthy statement on the club’s website overnight, saying: “I do not feel good when I see some fans talk very bad about Carlos.
“Today some people want to drive him out of our club, they cross the line with some abusive things they say.
“Now he is a very bad coach all of a sudden – maybe some people have short memories.”
Carvalhal’s exit means that both managers in the game between the Owls and Boro are no longer in work after Garry Monk left his position at the Riverside, despite winning, just hours after full-time.
