What is the least number of people who can play soccer?
It depends if you want to have a goalie or not. If you want a
goalie, you will need just two people (1 goalie and one forward).
If you don't want a goalie, just one person. They can serve as a
defense, goalie, and a forward. To play an actual game of soccer
(one person per position), you will need 4 people (1 goalie, 1
defense, 1 midfield, 1 forward).
