You have to go back to the 2011/12 campaign to find the last time that Pompey met their south coast rivals.
Both games during that Championship campaign finished all squad – although it was certainly the Blues fans who felt more like celebrating following the final whistle.
Joel Ward and David Norris both wrote their names in Fratton folklore by grabbing dramatic equalisers.
The latter’s is certainly the most memorable, with a superb volley deep into stoppage-time at a stunned St Mary’s.
But Southampton secured promotion at the end of that season and have remained in the Premier League since, despite a couple of recent flirtations with the drop.
And Pompey – who were then deep in financial crisis – were relegated, still trying to negotiate their way back up the divisions.
Both teams enter the game on the back of league setbacks, with Ralph Hasenhüttl’s men beaten by neighbours Bournemouth on Friday night.
It leaves them 13th in the top-flight table and that clash with the Cherries was labelled a derby by some.
Supporters of a Pompey or Southampton persuasion, however, know that this is the only true south coast derby.
TEAM NEWS
