Former Blues administrator Trevor Birch has been appointed at Bolton to aid the hunt for new investment.
Birch was a key figure in helping the Blues achieve community ownership during an April 2013 High Court victory.
As joint-administrator for BDO, formerly known as PKF, he won respect at the Pompey over his handling of the complex situation.
Chairman Iain McInnes once joked a statue should be erected at Fratton Park to mark his contribution.
Now Birch, who still visits Fratton matches on occasions, has joined struggling Bolton.
His remit is to act on behalf of the Championship club and their owner Eddie Davies in potential takeover talks.
It comes at a time when the club’s chairman, Phil Gartside, has been described as ‘seriously ill’.
A club statement added owner Davies ‘can’t provide any further funding’ following Bolton’s relegation from the Premier League (in May 2012) and the club’s failure to secure an immediate return to top-flight English football’.
It went on to add: ‘The role will see Trevor providing assistance to the board and owner, which will include managing negotiations with the various parties who have expressed an interest in purchasing the club.’
