The legendary forward look frustrated after he was substituted for Paulo Dybala in the second straight game. Sarri's move to send Dybala proved to be wise move as the Argentina international went on to score the winner for the old lady against Milan. Following the game, Capello talking to Sky Sport Italia, insisting Ronaldo 'must respect his team-mates'. “[Cristiano] is a great champion, nobody argues with that, but he hasn't dribbled past anyone in the last three years,” said Capello. “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.” The 73-year-old further said, “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,” he added. Juventus head coach Sarri also clarified that he has 'no problem' with Ronaldo and that he understands his frustrations. He explained that injury was reason behind Ronaldo’s substitution. “We must thank Ronaldo, because he made a sacrifice to be there at all tonight in a difficult situation,” Sarri following 1-0 win against Milan. |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,” Sarri added.
