Juventus midfielder Arturo Vidal is set for a grilling by coach Antonio Conte after returning late from international duty.
Vidal missed a flight from his native Chile, where his national side beat Ecuador 2-1 in midweek qualifying for the World Cup, and missed two training sessions after returning a day late to the Serie A club.
Juventus face Fiorentina away on Sunday, when the champions will be looking to reduce their deficit to Roma after the capital side stretched their league lead to five points with a 2-0 win over Napoli on Friday.
Conte did not say whether Vidal, one of Juventus's key players and the club's top scorer last season, would make the squad for Sunday's visit to Florence.
But the Italian said: "The Vidal question is very simple: I haven't spoken to him yet but I will be asking him why he returned a day late and missed two training sessions."
Conte added: "There are rules at this club, and the same rules apply to everyone."
