Throughout the entire season, Saints have had a problem with keeping out the opposition.
Ahead of this weekend's game with Bristol City, Saints had conceded a massive 67 goals in the league.
Three times this season the leaky backline have let in five goals - against Preston, Sheffield Wednesday and Hull City.
A seemingly endless run of injuries to centre halves certainly hasn't helped.
Last week Nigel Pearson swooped to land two experienced central defenders and with that in mind we want to know what your preferred back four is.
The rearguard has changed almost everyweek since August.
We want your ideal back four from the squad members who are currently able to play.
To help you get started, here's a list of the current squad members who have played - or still can - in defence this season, including those who are injured an unavailable.
- Alexander Ostlund
- Darren Powell
- Gregory Vignal
- Wayne Thomas
- Chris Perry
- Chris Lucketti
- Oliver Lancashire
- Jermaine Wright
- Jhon Viafara
- Andrew Davies (currently injured)
- Chris Makin (currently injured)
- Claus Lundekvam (currently injured)
Simply list the right back, left back and two centre halves that you would choose from the players above. Add your selection and your reasons why to the comments below and the best ones will be featured in this weekend's copy of The Pink.
