Huddersfield Town are among four English clubs interested in signing Celtic winger Jonny Hayes, who is out of contract next summer.
The 32-year-old, who moved to Parkhead for £1m from rivals Aberdeen two years ago, has become a peripheral figure for the Scottish Premiership champions, playing just 171 minutes of league football.
The three-year deal that he signed when he joined the club is up in the summer, and speculation has now emerged hinting at a potential move south of the border. TeamTalk
Hayes is said to be considering his future at the club, even though Bhoys manager Neil Lennon is keen to offer the winger fresh terms, despite his reduced role.
Cardiff are known to hold a long-term interest in Hayes, but the departure of Neil Warnock, and subsequent appointment of Neil Harris as manager, may result in their interest cooling, should the former Millwall boss be given a say on transfer dealings.
Huddersfield, meanwhile, are keen to boost their attacking options after a disappointing return to the Championship. The Terriers were relegated from the Premier League last season, but have failed to transition well to life at a lower level - resulting in the departure as manager of Jan Siewert.
Danny Cowley is the new man in charge at the John Smith's Stadium, and one of his primary concerns will be his side's lack of firepower in front of goal. His side have only scored 18 goals in their opening 16 Championship encounters, with much of the workload appearing to rest on the young shoulders of forward Karlan Grant.
Hayes could prove a useful option for Huddersfield if they can convince him that a move to Yorkshire is the best thing for his advancing career. He previously scored 23 goals in 165 appearances for Aberdeen, and was equally prolific in a far shorter stint at Inverness.
He is largely unproven in England, though, with a number of short loan spells failing to yield a single goal in the Football League.
