That’s interesting, would these pre season tours be booked a year or two in advance or are they that committed to growing the ‘brand’ they don’t care who’s out there?
@Skyblueweeman might know a little more
EPL teams pre-season tours can be booked a year or two in advance but this is rare. They tend to be tied into sponsorship deals so if one of your main sponsors is a Thai company for example, you'll likely head out to Thailand as part of your preseason.
For the majority of clubs - all EFL and some EPL, clubs only start looking around Dec time for the following summer. I know I was speaking Cov about Spain in January and not everything had been sorted then.
Clubs want to get a feel of how they're doing in the league. If it's looking like a good season, they might consider a trip abroad or if they're having a stinker and looking at a relegation battle then they'll shelve such plans and do a UK based preseason.
There are exceptions to the above to be fair but that's my experience with all the teams I've worked with.
