According to reports from the Daily Mail, Celtic are interested in signing George Baldock from Sheffield United and have made the first move to sign the right-back.
The Bhoys are looking to bolster their defence, especially the right-back area in the summer, and have identified Baldock as a potential target.
The former Milton Keynes defender made 25 appearances last season for the Blades and helped the club achieve promotion to the Premier League.
Interestingly, he is willing to ditch Premier League football next season to join the Scottish Premiership champions.
