Michael Johnston has completed a £3m permanent move to West Bromwich Albion.
The Baggies have this afternoon confirmed this signing of the winger, who pens a four-year-deal in the Midlands.

Johnston had the opportunity to join several sides south of the border such as Burnley and Sheffield United, but opted to sign for the club he was on loan at last season.
Indeed, the Ireland international spent the second half of the 2023/24 campaign at The Hawthorns and truly found his feet, scoring seven goals and assisting two in 20 games.
He will look to rediscover such form after joining the club permanently.
For Celtic, the 25-year-old made 93 first-team appearances, scoring 13 goals and assisting 12 along the way.
He won 13 major trophies for his boyhood club, but now moves to the English Championship in search of regular minutes.
Everyone at Celtic will wish Johnston all the best as he takes the next steps in his career.
