The Portuguese forward was visibly frustrated after he was brought off in the 55th minute for Paulo Dybala, making it the second game in a row that he has been substituted.
However, Sarri’s change proved to be the correct one as Dybala went on to score the winning goal with Capello insisting Ronaldo ‘must respect his team-mates’.

Corriere dello Sport and Tuttosport also focused on Ronaldo’s reaction to being brought off
‘[Cristiano] is a great champion, nobody argues with that, but he hasn’t dribbled past anyone in the last three years,’ Capello told Sky Sport Italia.
‘At the moment he isn’t at his best and it is normal to replace him. Sarri doesn’t need to be brave or show his personality to make that change.
‘It’s not nice that he didn’t sit on the bench [after being taken off] and argued with Sarri.
‘One has to be a champion even when he is replaced, not only when things are going well. He must respect his team-mates.’
Many Italian news outlets focused on Ronaldo’s reaction to being substituted, with La Gazzetta dello Sport and Corriere dello Sport describing the former Real Madrid star as ‘furious’.

Juventus goalkeeper Wojciech Szczesny sympathised with his team-mate after the game, by claiming that he would have reacted the same if he was subbed off early on in the second half.
The Poland international was asked by Sky Sport Italia if he was concerned that Ronaldo would leave the club to which Szczesny responded: ‘We are not worried, I believe that when a player of this level is replaced after 50 minutes it is normal that he gets a little upset.
‘Right now he is not very well, but nobody can doubt him. He will always make a difference. All the same, I would do the same.’

Sarri also clarified after the encounter that he has ‘no problem’ with Ronaldo and that he understands his frustrations.
The Italian boss explained that injury was behind the reason why he brought Ronaldo off in the second half.
‘We must thank Ronaldo, because he made a sacrifice to be there at all tonight in a difficult situation,’ Sarri explained.

‘He did everything possible to play, but I saw he was not well and thought it best to take him off.
‘It’s only natural a player is going to be irritated to leave the pitch, especially when he worked so hard to be there.
‘Over the last month, he has had this little knee problem, he had a knock in training and it hurt the collateral ligament.
‘When he trains at high intensity or plays, it unbalances him, so he ends up overcompensating and it damages the calf and thigh muscles.
‘It is affecting his performances and he is not at his best at the moment.
Sarri insisted that Ronaldo had been injured and that was why he took him off the pitch
‘All players who are trying to give their best will have at least five minutes of being annoyed when they are substituted, but a coach would in general be much more worried if he didn’t seem upset.’
Ronaldo also looked unhappy after being taken off during Wednesday’s Champions League match at Lokomotiv Moscow, although Sarri said it was to avoid risking injury as the 34-year-old had complained of knee and thigh problems.
Gazzetta dello Sport said Ronaldo left the stadium before the final whistle on Sunday evening.
Juventus, chasing a ninth straight Serie A title and unbeaten in all competitions under Sarri, who took over before the season started, moved to 32 points, a point ahead of Inter Milan who briefly went top after a 2-1 home win over Verona on Saturday.
