Alfie Mawson looks set to arrive at Swansea City to bolster Francesco Guidolin's defensive options.
Swansea City has agreed an undisclosed fee for Barnsley defender Alfie Mawson.
The Welsh club has been on the lookout for a center back since captain Ashley Williams left for Everton this month.
Mawson, 22, joined Barnsley from Brentford in June 2015 and scored six goals in 48 league appearances as the Tykes won promotion to the Championship via the playoffs.
Swansea is yet to agree to personal terms with Mawson and it is unclear whether Francesco Guidolin is still on the lookout for another defender with top-flight experience.
