Southampton are discussing the possibility of going on a commercial tour during pre-season.
Saints are discussing the possibility of a commercial tour, with the USA looking the most likely destination, and Koeman is reportedly open to the idea.
However, the Dutch boss wants to ensure that the tour happens at a stage where it will not harm their chances when competitive football starts up again.
“If they ask me to go to America for one week, ten days, ok, but not the last ten days before starting the Premier League, not the first ten days, and then it’s a possibility, because I think the most important always is the football side," he said.
“I know and I realise that the money, the commercial – but we need to be fresh at the first day when the Premier League starts.”
The Premier League's demanding schedule makes it difficult for teams to rectify faults in their squad on the training ground over the course of the season.
It means that pre-season is vital to a team's chances, as it is the longest period of time where a manager can solely focus on preparation work.
Koeman shouldn't have too much to correct over pre-season, as Southampton have been hugely impressive this year, but he will face a tough task in the 2015/16 campaign.
The Saints have raised expectations with their performances this term and will be determined to ensure that their standards do not slip next year.
