Hermann Hreidarsson is poised to complete a move to Coventry this weekend.
The News can reveal the 37-year-old fans’ favourite is set to clinch a permanent switch to the Championship strugglers for what is likely to be a free transfer.
Hreidarsson is out of contract at the end of the season and is not part of Michael Appleton’s plans.
Once completed, the deal will allow Pompey to bring in a new face to bolster their squad.
The Blues have been told by the Football League that they must let a player leave before anyone can be signed this month.
Hreidarsson has become a bit hit with the Fratton faithful since joining Pompey from Charlton in 2007.
But he has been out of the first-team picture this season despite the club having the smallest squad in the Football League.
