He is set to join Kyle Bennett and Gareth Evans in the Pompey 100 club.
And Christian Burgess admits that he feels at home at Fratton Park following his 2015 switch from Peterborough.
The centre-back will rack up a century of appearances for the Blues if he features against Oldham on Saturday.
But he is more concerned with securing a second successive victory than celebrating any personal achievements.
Burgess said: “It’s a nice milestone, but it’s not something that you look out for when you first join a club.
“That’s especially the case in the lower leagues because players at this level do tend to move about a lot.
"It’s nice to be settled in one place and this is probably the first time I’ve been able to say that."
“But it’s nice to be settled in one place and this is probably the first time I’ve been able to say that.
“There have been too many games to select my favourite, but Notts County and Cheltenham last season would be up there. Leyton Orient away on my birthday when I scored is another.
“It’ll be good to get to 100 appearances, but there’s a long way to go season and I’m just focusing on trying to get the win.”
Pompey produced a defensive masterclass in their 3-0 win over Bristol Rovers earlier in the week and Burgess knows they will have to show those battling qualities again.
He said: “It’s a step up in quality this season. We’re facing better teams, so there are times when you have to grind it out.
“Bristol Rovers probably had the better of us for the first half-an-hour on Tuesday night and you could hear the crowd cheering every block and clearance.
“It takes a bit of time for everyone to gel into this division – and also to understand each other and gain confidence.
“Teams came here and sat back last season, so we had it easy from a defensive viewpoint. Now it’s just about consistency because we’ve shown that we can handle that.”
