Swansea City have launched a bid for Barnsley defender Andy Yiadom, according to the Sun.
The 25-year old has been the subject of a failed bid from the Welsh club.
However, the Swans have now returned with an increased offer of £3m.
Huddersfield Town also have an interest in Yiadom after having three bids rejected by the Championship club.
The Ghanian made league 32 appearances for the Tykes last season.
