CELTIC are back on the trail of a goalkeeper they first targeted a decade ago when Martin O'Neill was still in charge of the Parkhead club.
Swedish international Andreas Isaksson is now 30, but has re-emerged on the radar of current Hoops boss Neil Lennon.
With Fraser Forster still deliberating on the four-year contract offered to him, Lenny is considering all of the options identified.
Along with Craig Gordon, Isaksson is on that list, and both keepers are now free agents after reaching the end of their contracts at Sunderland and PSV Eindhoven respectively.
A former international team-mate of Johan Mjallby and Henrik Larsson, Isaksson previously pushed former Hoops keeper Magnus Hedman out of the No.1 jersey for Sweden.
Since Celtic's initial interest in him when he was a rising start with Djurgarden, he has played for Rennes and Manchester City before moving to PSV.
Isaksson took his tally to 96 caps when he played in all three of Sweden's games at the finals of Euro 2012.
Lennon is keen to sign another experienced defender and a striker, with Bordeaux president Jean-Louis Triaud encouraging Celtic club to make a move for their centre-back Michael Ciani.
The price would be around £1million for the 28-year-old who, just 18 months ago, was linked with a £10m move to Arsenal and is now also attracting interest from Newcastle, Wigan and Seville.
