Carlos Carvalhal will leave his position as Swansea manager at the end of the season.
The Swans look almost certain to be relegated from the Premier League after a run of eight games without a win, including a defeat to fellow strugglers Southampton on Tuesday night.
The Welsh side need to beat Stoke on Sunday and for Saints to lose at home to champions Manchester City, with a 10-goal swing in their favour, to stay up.
Swansea do not plan to renew Carvalhal's contract.
Carvalhal's reign began with a win over Watford and they followed that up with victories over Liverpool, Arsenal, Burnley and West Ham. But their form has collapsed since then.
Carvalhal is due to face the media today.
Swansea, meanwhile, have announced that long-serving defender Angel Rangel will be leaving.
The 35-year-old intends to continue playing elsewhere before one day returning to the Welsh outfit, saying: "I will look somewhere else. When I am 37 or 38 it will be time to call it a day and hopefully I will come back and help in another way."
