Ronald Koeman won the European Cup with PSV Eindhoven in 1988 and Barcelona in 1992. Along with that, the 52-year-old has managed in the Netherlands, Portugal, Spain and now England, applying his trade in multiple countries and increasing his know-how of different football cultures across Europe.
Arsenal's 12th FA Cup triumph over Aston Villa on Saturday confirmed the Saints' place in Europe and Jimmy Case, who played for Southampton between 1985-91, backs Koeman to impress.
"With European competition Koeman's been there, he knows all the tricks and he's managed abroad," Case told BBC Radio Solent.
"I'm sure that tactically he's more than capable of getting a team to perform in Europe, but it's all about the squad."
Southampton's last European experience came in the first round of the Uefa Cup in 2003-04 when they lost 2-1 on aggregate to Romanian side Steaua Bucharest.
They will be hoping for a better run in next season's Europa League and that may require keeping hold of key players such as Morgan Schneiderlin, who is receiving interest from Manchester United, as per the Metro.
Case himself has a wealth of experience in Europe having won the European Cup three times with Liverpool, as well as the Uefa Cup and Super Cup. At Southampton he made over 200 appearances in a six-year period.
"Koeman has got his sidekick Sammy Lee, who's been in the competition as well, so it's well set up," he added.
"If you've not generally played in Europe consistently it's a new venture. I think for Southampton it could be healthy."
