19-year-old Cubasi has become a key player in Barcelona's defense. The center-back, a product of La Masia, made his first-team debut for Barcelona in 2024 and quickly established himself as a core member of the team's defense.
Outside of football, Kubasi also values rest and study. In an interview with RAC1, he revealed that he sleeps about nine hours a day, trains in the morning, and attends classes from 3 pm to 8 pm, with adjustments only made on Champions League match days.
In 2025, Cousais began pursuing a degree in Business Administration and Management. Regarding social media, he stated that he doesn't pay excessive attention to online comments: "I don't pay much attention to social media. In the world of football, everyone likes to express their opinions on what they see and how you play, and I don't think it's necessary to care too much about these things."
In terms of diet, Kubasa also maintains a relatively disciplined approach. He says he plans his own meals and tries to ensure a variety of foods. However, he doesn't completely reject the foods he likes.
“I try to reward myself after every game; if I play well, I’ll have a hamburger,” Cubasi told Marca in an interview.
