Pompey have appointed Jake Wigley as the club’s new first-team coach.
And former Blues skipper Paul Robinson will also combine his playing duties at the Hawks with a role in the Blues' backroom team.
Wigley, the son of ex-Pompey winger Steve, has spent the past four years coaching at Nottingham Forest.
He recently worked with the under-18s side at the City Ground, while he also had a stint helping with first-team duties under Stuart Pearce and Dougie Freedman between 2014-2016.
Wigley was previously at Bolton Wanderers as a youth development coach and is a sports coaching science graduate from the University of Chichester.
He holds both the UEFA A Licence and Advanced Youth Award.
Wigley succeeds former first-team coach Robbie Blake - whose contract was not renewed this summer by boss Kenny Jackett.
Meanwhile, Robinson returns to the club he spent the 2014-15 campaign with.
The centre-back joined Lee Bradbury's Hawks earlier this month after being released by AFC Wimbledon.
However, because the Westleigh Park outfit are remaining semi-professional ahead of their maiden National League campaign, it's allowed Robinson to take up a backroom role at Fratton Park.
