The 20-year-old has agreed to a contract that will keep him in place until the summer of 2026, with a 12-month extension option.
After moving to Turf Moor from Stoke in 2020, Sassi captained several of the Clarets’ youth teams. His first professional contract, which he signed in 2022, is only scheduled to expire the following summer.
The midfielder, who joins the Seasiders on loan from Sheffield Wednesday for the duration of the season, is George Byers’ second addition to the team on Deadline Day. The center back becomes the new player. This comes after Ryan Finnigan, who was signed by Southampton on Wednesday for an undisclosed sum, was also signed.
With Matthew Pennington, Callum Connolly, Marvin Ekpiteta, James Husband, and Olly Casey vying for spots in Neil Critchley’s starting XI currently, Sassi’s signing may bring even more competition for the present back three.
