Saints have ditched plans for a high-profile away friendly this summer, but will now begin pre-season overseas.
The club will play two low-key matches next week, starting in the Netherlands and then moving to Belgium.
They will begin with a fixture against Dutch fifth-tier side EHC Hoensbroek on Tuesday, with kick-off set for 7pm local time (6pm UK) at SportPark de Dem, in Hoensbroek.
Ronald Koeman's team then face Belgian third division outfit KSK Hasselt, at the Stedelijk Sportstadium, on Thursday (7pm local/6pm UK).
The team will wear the new all-navy away strip, which was unveiled last night, for both matches.
Tickets for the first game cost between €5 and €8 on the turnstiles.
For the second match, tickets are available from the Stedelijk Sportstadium ahead of the contest, priced at €10.
Saints had originally said they were organising a high-profile away game against notable European opposition between the friendlies against Brighton and Bayer Leverkusen, but that is no longer taking place.
