I know Sarri plays an interesting brand of football but with Chelsea you never know when it comes to manager's longevity. Plus, us Croatians just prefer Italy in most cases, far closer culture, closer to home etc. Ask any kid here that is the same age Mateo is and they will likely tell you they cheared for a Serie A side, hardcore football fans I know are mostly fans of Italian sides, be it Juve, AC, Inter, Roma, Fiorentina, Parma etc. And if you liked an English side it was Arsenal, Utd or Liverpool, but those guys are far rearer.
