CARETAKER HEAD COACH - ALAN SHEEHAN

Alan Sheehan joined Swansea City as assistant head coach in June 2023, taking up the position within Michael Duff's coaching staff.
Sheehan, 38, who has held first-team coaching positions at Luton Town and Southampton, enjoyed a lengthy playing career that saw him feature for Leicester, Mansfield, Leeds, Crewe, Oldham, Swindon, Notts County, Bradford, Peterborough, Luton, Lincoln and Northampton.
The former left-back also won five caps for the Republic of Ireland Under-21s, and held a player-coach role with Oldham before his move into full-time coaching with Luton in 2022.
He became caretaker head coach when Duff left the club in December 2023 and led the side tremendously well to take 11 points from a possible 21 during a congested schedule prior to Luke Williams' appointment as head coach in January 2024.
Williams' arrival saw Sheehan revert to his position of assistant head coach, before having a second spell as caretaker boss in February 2025.
MARTYN MARGETSON - HEAD OF GOALKEEPING

Martyn Margetson rejoined Swansea City as head of goalkeeping in July 2023.
Margetson was previously on the club’s coaching staff between 2019 and 2021 and took up a position as part of Michael Duff’s new-look backroom team, remaining in place following Luke Williams' appointment.
He is currently goalkeeping coach in Gareth Southgate’s England set-up, where he has helped the Three Lions reach the semi-finals of the 2018 World Cup and the Euro 2020 final.
Margetson hails from Port Talbot and started his playing career with Manchester City, joining their youth system in 1988.
He went on to make 60 first-team appearances for the Maine Road side, while also having spells with Bristol Rovers, Bolton, Luton Town, Southend, Huddersfield and Cardiff, becoming player-coach at the latter and moving into a goalkeeping coach position after hanging up his gloves in 2007.
Margetson, who was capped by his country against Canada in 2004, went on to join the Wales national set-up to work with Gary Speed in 2011.
He remained involved under Chris Coleman as the Dragons enjoyed an unforgettable run to the semi-finals of Euro 2016.
Margetson then made the switch to England in August 2016, initially working under Sam Allardyce and then remaining in Southgate’s backroom team.
At club level, he moved to West Ham in 2014, before returning to Cardiff. He has since worked at Crystal Palace, Everton and Swansea.
Margetson combines his ongoing England duties with his position in Swansea's coaching team, and signed a new three-year contract with the Swans in the summer of 2024.
