Celtic defender Stephen Welsh is set to become Swansea City's first summer signing. The 26‑year‑old graduated from Celtic's academy and logged 70 first‑team appearances for the Glasgow club. Last season he spent most of his time on loan at Motherwell, adding 31 Scottish Premiership games to his résumé. A brief stint in Belgium with Mechelen and an early‑career spell at Morton round out his experience.

Swansea head coach Vitor Matos sees Welsh as a solution to a thin central‑defence department. Ben Cabango and Cameron Burgess anchored the back line last term, while Ricardo Santos struggled for minutes and Kaelan Casey departed after his West Ham loan ended abruptly in January. Adding a player with domestic and continental loan exposure gives Matos more options heading into the Championship campaign.

Welsh arrives with a solid track record and the chance to cement a regular starting berth. His versatility across the back four should allow Matos to rotate without compromising stability. For Swansea, securing a home‑grown‑type defender before the transfer window closes strengthens a squad that struggled for depth last season, and Welsh’s debut will test that resolve.
