Cubarsi opened up about his daily routine in an interview with RAC1, saying: "I'm studying the second year of social high school. I train in the morning and go to class at three in the afternoon. The teachers from León XIII come to La Masia and I have class until eight in the evening. If there's a Champions League, I have to ask for notes or be attentive the next day to catch up. Sometimes it's difficult to study, but I'd like to study a degree in marketing or business administration, but first I have to finish high school and then we'll see."
