Paul Robinson revealed it was a ‘straightforward’ decision to seal a permanent Pompey move.
And the Blues are also striving to rubber-stamp Matt Tubbs’ switch this morning.
Central defender Robinson has penned an 18-month deal after long-time employers Millwall agreed to terminate his contract.
Despite interest from an unnamed fellow League Two club, the 33-year-old was adamant he wanted to remain at Fratton Park following a successful loan spell.
Tubbs yesterday cancelled his deal with Bournemouth to become a free agent.
Pompey will now wrap up his move in time for him to be considered for Saturday’s trip to Newport County.
Robinson, though, is already over the line.
He said: ‘It was an extremely straightforward decision from my point of view.
‘When I signed on loan initially there was a possibility of making it longer, but I think it took coming on loan for the situation at Millwall to become clear to me.
‘In the summer I had a couple of League One clubs in for me, while this month a League Two club made a firm offer.
‘But once Pompey offered me something permanent my mind was made up.
‘I have a good feeling about this place, it is the right club at the right time for me.
‘I had no hesitation, I’ve really enjoyed my five months here so far and get the feeling we are on the way to getting it right.
‘Obviously I have been in discussions with Millwall to settle my contract to make me a free agent.
‘In the summer every year it gets harder and harder, a lottery, so I wanted to take my future into my own hands and move it forward.
‘Millwall have been excellent, they allowed me to do that and Pompey were always the frontrunner when it came to joining a new club.
‘I had a great time with the Lions, but things change in football, they move on, and I’m looking forward to doing well with Pompey now.’
Robinson has made 25 appearances and scored once since arriving on loan on the eve of the campaign.
When available, he has been a regular at the heart of a defence which chopped and changed as the season has wore on.
Through it all, he has remained the Blues’ most consistent performer in the back four.
And the Fratton faithful have applauded his permanent arrival.
Meanwhile, Pompey are finally set to complete the long-awaited recruitment of Tubbs.
The 15-goal striker has attracted interest from Bristol Rovers, AFC Wimbledon and Southend, yet Fratton Park is his destination.
Based in Mudeford, Dorset, the 30-year-old’s preference has been to remain on the south coast and he will now add goals to a team which has struggled in that department.
