One of the main challenges anticipated with Flick’s transition to Barcelona is the language barrier. Flick, who does not speak fluent Spanish or English, faces communication hurdles. Hence, Thiago, who is fluent in German, English, and Spanish, will play a crucial role in easing this transition. He will act as an intermediary, facilitating effective communication between Flick and the players, and ensuring that the new manager's strategies and instructions are conveyed and understood.
