Skysports.com understands Ipswich are lining up a move for Celtic defender Lee Naylor.
Roy Keane is thought to be keen to bring in a new left-back and Naylor is thought to be his top target.
Naylor's future at Celtic looks uncertain with the former Wolves ace struggling to hold down a regular place in the side.
The 29-year-old has been forced to play second fiddle to Danny Fox this season and he could be tempted to move on in search of regular first-team football.
Celtic could be willing to let Naylor leave in a bid to raise funds for their own transfer plans and Keane could step up his interest in the player before the close of the transfer window.
