Reading play in a high line
Montero focused on Cubarsí's anticipation, interceptions and contribution to building attacks. Those qualities matter particularly when Barcelona push their defensive line forward and leave space behind it. He recalled the mistakes made during the defender's development after entering the first team at 17, arguing that Barcelona allowed him time to improve. Lamine Yamal provided another example of why early inconsistency should not end a young player's opportunities. Montero contrasted that patience with the demand for immediate results he perceives in Italian football.
Potential still needs development
The article places Cubarsí among five Golden Boy finalists, alongside Yan Diomande, Warren Zaïre-Emery, Lennart Karl and Estêvão Willian. Praise from a former player does not decide the winner. Montero also discussed Dean Huijsen, whom he helped develop at Juventus, while distinguishing the two defenders' characteristics. He considered them compatible for Spain without announcing a selected partnership. For Huijsen, adapting to scrutiny after joining Real Madrid and maintaining mental steadiness remain important. Across both assessments, Montero's central argument was that talent requires experience, support and time to mature rather than constant demands for instant perfection.
