According to Voetbal International, Romeu credits Xavi's understanding of football, ability to connect with players, and effective communication as key factors in his success. Romeu, who currently plays for Avispa Fukuoka in Japan, has first-hand experience of Xavi's coaching style, having played under him at Barcelona. "Xavi has a lot to offer on all these levels," Romeu said. "He's also very demanding when it comes to details that might seem small, but can make a big difference at the top level." Romeu also praised Xavi's ability to get the best out of players, citing Frenkie de Jong as an example. "He has a high opinion of Frenkie de Jong, and I'm sure he can get the best out of him."
