Sean Raggett has not missed a minute of football for Pompey so far this season.
And the defender has played a key role in a side that are yet to concede a single League One goal after four games.
Successive victories over Fleetwood, Crewe and Shrewsbury were followed by last Saturday’s draw at Doncaster.
Raggett is building a promising centre-back partnership with summer signing – and new skipper – Clark Robertson.
But he believes that the whole side deserve credit for the miserly defensive record boasted by the Blues.
The 27-year-old said: “We’ve had a good start to the season without conceding a goal – and that starts from the other end of the pitch.
“The forwards press really well and that takes the pressure off us, so it’s not just about the back-line and the keeper.
"We’ve had a good start to the season without conceding a goal – and that starts from the other end of the pitch."
“Our shape is all about defending from the front, but then also protecting our own box when we need to.
“Gavin Bazunu and Alex Bass have both played in goal this season and they’ve also come up with some good saves.
“I knew Clark already from when we were at Rotherham together and so the partnership perhaps hasn’t needed as much work.
“We both feel comfortable playing alongside each other and that’s a big thing when you’re looking to build an understanding.”
Next up for Pompey is a trip to face a Wigan outfit that includes former Fratton favourites Tom Naylor and Jack Whatmough in their ranks.
Raggett said: “They look a good side and we obviously know a couple of their players who used to be here.
“It will be nice to see them again and we still talk quite often, so I’m sure there will be a little bit of banter – we all want the bragging rights.
“Wigan have got a strong team and I think they’ll be right up there this season, so we know it’ll be a tough game."
