Hermann Hreidarsson has been welcomed back to Pompey with open arms.
The veteran defender has agreed a new Blues deal, despite interest from several other clubs.
The Iceland international also accepted a substantial reduction in terms to remain at Fratton Park.
Hreidarsson will now put pen to paper on a 12-month contract when he returns to England from Iceland.
The 36-year-old is expected to be back in training on Friday, having been given additional time off after playing international football this summer.
For Blues boss Steve Cotterill, it is another important recruit as he continues to strengthen his squad.
With Kanu, Liam Lawrence and Tal Ben-Haim also due back at the end of this week, playing numbers are rising.
However, Hreidarsson may not be ready to feature in Monday’s opening friendly against the Hawks.
Regardless, Cotterill is boosted by the return of the left-back.
He said: ‘We are really pleased about Hermann deciding to return.
‘He is a good lad who showed some real character coming back last year.
‘He has got another year’s deal so, hopefully, he will come back after a bit of a break refreshed and raring to go again.
‘We’ve given him a bit of a longer break like a couple of the others because they were still playing over the summer.
‘It is now only a matter of him coming back into the UK and signing the contract.
‘I expect that will all be sorted out in the next 48 hours.’
Hreidarsson arrived from Charlton in the summer of 2007 and has since made 121 appearances for Pompey.
