During the holidays, Alonso has taken on the role of coaching his son’s team for the Donosti Cup. The Donosti Cup is a renowned international football tournament that has been held in San Sebastian each summer since 1992.
The competition is taking place this week, and the team is currently topping their group. Alonso’s son Jon is not the only child of a football star on the squad, as Mikel Arteta’s son Gabriel also plays for the same team.
