The 24-year-old will be the second central defender to join the Clarets this summer after Jordan Beyer's loan move was made permanent last month.

Burnley will face Premier League champions Manchester City in their top-flight opener on 11 August.

There was an £8m release clause in O'Shea's contract but West Brom have opted to let him leave for less to generate income as they face up to financial realities without parachute payments.

O'Shea came through the Baggies' academy and broke into the first team in 2019 after loan spells at Hereford and Exeter City.

He featured regularly in the Premier League in 2020-21 and, despite missing six months of the following campaign with ankle ligament damage, has made more than 100 league appearances for the club.

Vincent Kompany's Burnley won the Championship last season to secure promotion back to the top flight at the first attempt.
