Skysports.com understands Celtic are eyeing a move for Sheffield Wednesday goalkeeper Lee Grant as a possible replacement for Artur Boruc.
The Scottish giants are looking for a new goalkeeper after letting No.1 Boruc leave for Fiorentina earlier this week.
Bhoys boss Neil Lennon is believed to be drawing up a shortlist of possible replacements and Grant is thought to be among his targets.
Sheffield Wednesday are facing a fight to keep hold of Grant following their relegation to League One last season.
A number of clubs including Wigan, West Brom and Burnley have all been linked with Grant, who has impressed during the last few seasons at Hillsborough.
Wednesday would like to keep Grant, but they would find it hard to reject a sizeable offer for the 27-year-old due to their financial situation.
