Daniel van Buyten's agent has hinted the Bayern Munich defender could be tempted by a move to Newcastle United.
Reports have claimed that the Belgium international is among the players new Magpies boss Kevin Keegan is looking to sign before the close of the transfer window.
Van Buyten's future with Bayern is uncertain, with the centre-half struggling to secure regular football this season.
He recently admitted that he may be interested in a switch to Scottish champions Celtic, while Premier League clubs are also in his trail.
The former Marseille stopper played under Keegan at Manchester City after spending the second half of the 2003/04 season with the club.
And, according to his representative Christophe Henrotay, a reunion with Keegan at St James' Park would not be ruled out.
"Daniel would like to carry on doing his job at Bayern, but I have said to Kevin, 'Anything can happen, the truth today is not the truth tomorrow'," said Henrotay in The Guardian.
"And Daniel appreciated Kevin's management at Manchester City."
