The Serie A leaders found a way to win without their Portuguese attacker, who was replaced for a second game running
Juventus coach Maurizio Sarri conceded he would be worried if Cristiano Ronaldo wasn't upset after once again being substituted on Sunday.
The 34-year-old was replaced by Paulo Dybala in the 55th minute during Juve's Serie A clash with AC Milan and immediately made his way up the tunnel after coming from the pitch.
Reports in Italy also suggested Ronaldo left the stadium three minutes prior to the end of the match - which Dybala ultimately decided with a 77th-minute strike.
