Huddersfield Town are set to make an improved offer for Barnsley defender Andy Yiadom, Sky sources understand.
The Premier League new boys have already had a bid worth more than £1m turned down by the Sky Bet Championship side.
Swansea City, who signed Alfie Mawson from Barnsley last season, and QPR are also interested in the right-back who has played twice for Ghana.
Yiadom moved to Barnsley from Barnet last summer and has 12 months left on his contract.
The 25-year-old, who came through the non-league ranks with Hayes & Yeading and Braintree, made 32 Championship appearances in his first season at Oakwell.
