Russell Martin has signed a new three-year deal at Southampton.
The head coach, appointed in June 2023, took the Saints back to the Premier League at the first attempt, beating Leeds 1-0 in the Championship play-off final.
Assistant Matt Gill, first-team coach Carl Martin and goalkeeping coach Dean Thornton have also agreed fresh contracts.
First-team coach Colin Calderwood, sports scientist Rhys Owen and analyst Ben Parker have signed new deals too.
Martin said: "I'm really grateful to the owners and to Phil [Parsons, chief executive]. Once the season was finished, they expressed a desire to discuss a long-term plan with myself and the coaching staff.
