  In this paper, we study interaction dynamics in the game of football-soccer
in the context of ball possession intervals. To do so, we analyze a database
comprising one season of the five major football leagues of Europe. Using this
input, we developed a stochastic model based on three agents: two teammates and
one defender. Despite its simplicity, the model is able to capture, in good
approximation, the statistical behavior of possession times, pass lengths, and
number of passes performed. In the last section, we show that the model's
dynamics can be mapped into a Wiener process with drift and an absorbing
barrier.
