Swansea have sacked head coach Michael Duff with the club sitting 18th in the Sky Bet Championship
The 45-year-old departs the Swansea.com Stadium following a winless run of five games and just one win from their last eight after their recent 1-1 draw against Huddersfield.
Duff was appointed in June, having led Barnsley to the Sky Bet League One play-off final last term, and was in charge for less than six months following a difficult spell in charge.
Assistant head coach Martin Paterson follows Duff out of the exit door with immediate effect, while fellow assistant head coach Alan Sheehan will take interim caretaker charge.
Swansea chairman Andy Coleman released a statement on the club's website, which read: "This was a very difficult decision and one that was given considerable thought and attention.
Michael Duff's inspirational coal mine trip rousing Barnsley's promotion effort"I acknowledge that there has been a significant amount of change at the club, both on and off the pitch, during Michael's tenure. I consistently asked for patience as we gave him time to implement his plans and bring the squad together.
"Unfortunately, we have seen neither the results that we expect nor the progress from the squad that we need. I believe it is now in the best interests of Swansea City to make a change of head coach."
