Sonny Bradley highlighted facing Pompey as his anticipated game of the season.
And the former Blues defender believes an ongoing rivalry between the his old side and Plymouth is the reason behind that.
Bradley made 39 appearances following a move to Fratton Park from Hull in 2013.
He knows what to expect when he returns to PO4 tomorrow.
Bradley told the Plymouth Herald: ‘It’s one that I always look forward to. It’s a big game.
‘I am sure we will fill the away end at Portsmouth. It will be bouncing, and the Portsmouth fans will be the same.
‘I’m sure they will want to beat us just as much as we want to beat them.
‘It will be a highly-competitive game but we have proved this season we can go away to big teams and get good results.
‘There will be 15,000-16,000 there I would imagine and if we are up for it, like we were at Bradford, I don’t see any reason why we can’t go there and get a result.
With 170 miles of road between the clubs, Bradley dismissed the suggestion the match is a derby - but feels it will have a similar feeling to one.
He said: ‘I think over the last five or six seasons Portsmouth and Argyle have been in a similar position.
‘They are big clubs which probably don’t deserve to be in the league they are in, but it’s the way it is.
‘They (Portsmouth) travel well when they come here and bring a load of fans, and we do the same to them.
‘I don’t think it goes down as a derby, but it certainly feels like one when the game kicks off.
‘I will make sure the boys are up for it and remind them how important it is to us.’
