The Blues hero has outlined his ambition to make an emotional return to Fratton Park.
And the attacking great has vowed he still can have a big impact at the club he shares a special bond with.
Lualua spent three years laced with unforgettable memories in the Premier League with Pompey.
And the 36-year-old vowed he still has the sharpness to make an impact with his mercurial skills again.
Speaking to The News, Lualua said: ‘From day one I’ve always said I want to finish my football in Portsmouth.
‘It’s Portsmouth or Colchester, where I started, for me.
‘I had that freedom to enjoy myself on the pitch here and off it.
‘There’s something special about this city, the place and the fans.
‘You never forget where you have your good times and best memories. This is home for me.
‘I feel I gave everything in my time at the club – and I’d still like to do that again.
‘I’ve been thinking about it for a long time. It’s not because I’m a hero. I made a name in Portsmouth, though.
‘I wouldn’t be prepared to come back and taint that because people remember what I did.
‘I’m not prepared to do it because I’m Lua and I made a name. No.
‘If I was to come back I want to be able to run and bring something to the team. I want to help.’
Lualua is currently training with QPR where he has spent six weeks and more than held his own against Championship players.
That’s convinced him he still has much to offer.
Lualua said: ‘I’m training with QPR and the coaches can’t believe I still have it.
‘Okay, I might not be the Lua who was running fast everywhere but I still have that explosiveness.
‘You know how to use your experience and be clever. I’d be here to compete.
‘They say the Championship is the hardest physically and I’m still competing with them.
‘Ian Holloway keeps telling me Teddy Sheringham played until he was 40.
‘I keep telling him I’m not Teddy Sheringham! But I do believe I have at least two years left in me.
‘You never know. A lot of experienced players say don’t stop until you can’t go anymore. You will live to regret not trying to do it.
‘The moment I can’t do it is the moment I stop playing – but I still have the energy.’
