Swansea City have agreed an undisclosed fee for Barnsley defender Alfie Mawson, who is set to hold talks over personal terms with the Premier League side.
The 22-year-old moved to the Tykes from Brentford in June 2015 on a three-year deal, and had also been linked with Sunderland this season.
He scored seven goals to help Barnsley win the 2015-16 League One play-offs and Football League Trophy.
Mawson has scored two more for Barnsley in the Championship this season.
