FAQ: Indoor Soccer World Cup. The tip means that Guatemala will not lose by a margin greater than 3 goals.
Reasoning: The odds are distorted due to France’s big reputation in football. However, in indoor soccer, they have never been a top team, as shown by their debut in the futsal World Cup. Their players are considered semi-pro at best, with some practically amateurs. Despite some surprisingly good results this year (e.g. beating Spain), they also had some ugly defeats. They even drew with Costa Rica, who are roughly on par with today’s opponent: Guatemala. While Guatemala finished third in their group, they have had some impressive recent victories (e.g. beating Thailand). France topped their group, but with no significant opponents beyond Croatia. I believe Guatemala is not inferior to them in any way. This could turn into a close match.
Final result: France won the match 6-3 => the tip WON!
