Does any Premier League club dismiss a permanent manager or head coach on or before 13 Sep 2026?

Three of the last eight seasons had a Premier League sacking by 30 September, and four of nine since 2017-18. The early ones share a shape: three or four games, and either a rout, a single point, or a public row with the owner. What raises the number this year is the state of the league rather than the calendar: tenure is at a record low, nine dressing rooms have a manager they had not worked with in July, and once the window shuts every board can measure its head coach against the squad it paid for. What holds it down is that a board which has just hired, backed and paid for a manager has every reason to wait for winter.
