Barry Douglas signed for Leeds United from Wolverhampton Wanderers in July 2018 for an undisclosed fee.
Starting his career at Queen's Park, Douglas also had stints with Dundee United, Lech Poznan and Konyaspor.
He joined Leeds on the back of helping Wolves to win promotion from the Sky Bet Championship in the 2017/18 season.
In Douglas’s final season with Wolves, he provided the most assists in the Championship.
His first season at Leeds was marred by injury as he only started 21 times. Douglas will be hoping to bounce back from injury ahead of the new season and recapture his form from the 2017/18 season.
