Swansea City have made a £3 offer for Barnsley full-back Andy Yiadom.
Paul Clement's side are looking to bolster their defence after a leaky campaign last season and according to The Sun, the Swans have now moved to the top of the list ahead of Premier League new-boys Huddersfield in the race for the 25-year-old's signature.
David Wagner's side have seen three bids, with the latest being a £2m offer rebuffed from the Yorkshire side with them waiting for a club to match their valuation of their man.
Further interest has been shown from Championship sides Reading and QPR, but with both Swansea and the Terriers now both showing an interest a move to the top-flight will surely be difficult to turn down.
The Tykes have been keen to keep Yiadom at Oakwell, but with his contract expiring next summer, they could sell him for a cut-price fee rather than losing him on a free transfer.
The full-back who can also play as a winger has made an impressive rise from non-league playing for Hayes and Yeading and Braintree before moving to Barnet where he made a major impact and won promotion to the Football League.
After joining Barnsley on a free transfer last summer, he impressed in his first season in the second-tier earning his first call-up to the Ghana squad in this year's Africa Cup of Nations, featuring twice for the Black Stars in Gabon.
