Swansea have beaten the transfer deadline by some margin to complete the signing of Barnsley defender Alfie Mawson.
The 22-year-old has signed a four-year contract after moving from South Yorkshire for an undisclosed fee, and could bring to an end Francesco Guidolin’s search for a new central defender.
The two clubs reached an agreement on Friday but the deal had remained subject to personal terms being finalised, which has now been rubberstamped.
Mawson played 58 times for Barnsley last season after joining from Brentford, helping them win both the Football League Trophy and Sky Bet League One play-off final.
He began his career with Reading before joining Brentford as a youngster, spending time on loan with Maidenhead United, Luton Town, Welling United and Wycombe Wanderers.
He is now the latest in a series of young Barnsley defenders to progress to the Premier League, following Manchester City’s John Stones and Everton teenager Mason Holgate.
