Pompey have confirmed the arrival of Anthony Williams as new goalkeeping coach.
The 36-year-old also takes up the role of Richie Barker’s assistant as the Blues boss shuffles his backroom.
Steve Allen left his job as physio/assistant manager on Monday and has now joined Bristol City.
Barker had attempted to persuade him to remain in a physio role but he opted for a fresh start.
On the same day, Dave Coles’ four weeks back at the club ended after being informed he was no longer required.
Coles had been brought in on a short-term basis by Guy Whittingham and was not on a contract.
Now Williams has arrived, a trusted ally of Barker, having worked alongside him at both Bury and Crawley.
The Welshman also served with director of football Steve Coppell with the Reds until he was shown the door on the same day as Barker.
Williams has been involved in training since Monday and will be beside Barker in the Blues dug out on Saturday for the trip to Bristol Rovers.
Ironically, the former goalkeeper spent time on loan with the Pirates in the 1998-99 campaign, making nine appearances.
Williams represented 13 clubs in his playing career with his time at Hartlepool standing out during a 146-match period.
Welsh Premier league side Neath was his last club in the 2009-10 season.
