Cristiano Ronaldo is said to have left the Allianz stadium before the final whistle Juventus1-0 victory for Serie A Milan replaced last night after the second game in a week.
Paulo Dybala replaced Ronaldo on 55 minutes and the Argentine striker scored the winning goal 22 minutes later to keep Juventus in Serie A ahead of Internazionale.
The fivefold balloon d'Or winner Ronaldo looked dejected as he got out and addressed a few words to his coach Maurizio Sarri before going to the dressing rooms.
Sky Sport Italia reported that the 34-year-old former striker Real Madrid and Manchester United had left the stadium three minutes before the end of the match.
However, Sarri said he did not know if Ronaldo, who moved from Juventus to Madrid for £ 88m last summer, had left the stadium prematurely.
"Disrespectful to his teammates? As I said, I do not know, "said Sarri. "If it's true that he left before the end, it's a problem that needs to be solved with his teammates."
"I have no problem with Cristiano, he should be thanked for making himself available even though he was not in good shape," said Sarri, the former head coach of Chelsea and Napoli.
"Last month he had knee problems and that's a little problem for him."
Ronaldo had reacted strongly after being substituted by Lokomotiv Moscow in the 2-1 victory of his side midweek when Juventus entered the Champions League last year.
"It is important that he has made himself available. If he gets angry when he comes out, that's part of the game, "continued the Juventus coach.
"It's only natural that a player is irritated when he leaves the field, especially if he has worked so hard to be there."
"All players who try to do their best have at least five minutes to annoy themselves when they are substituted, but a coach would generally be much more worried if he were not angry."
Juventus, who drew a ninth consecutive Serie A title and was unbeaten in all competitions under Sarri, who took the lead before the start of the season, edged up 32 points, one point ahead of Internazionale, who scored on Saturday after a 2-1 win. Home win against Verona took the lead.
Milan's problems continued when they fell to 14th place after their ninth away defeat by Juve in Serie A with 13 points. However, they performed better and had better chances in the first half. Failed striker Krzysztof Piatek headed home from an unmarked position, and Lucas Paqueta's header in the loop forced Wojciech Szczesny into a difficult save.
Hakan Calhanoglu tested Szczesny in the second half with a free kick before Dybalas brilliant moment ended the match. In injury time he almost met again, but was rejected by Donnarumma.
Elsewhere in Europe Seville took the loot in a highly competitive city derby on Sunday, beating Real Betis 2: 1 away to advance to fourth place in the league. Julen Lopetegui's side took the lead in the 14th minute when Argentinian Lucas Ocampos brought the ball into play and fired under Betis keeper Joel Robles. Betis' top scorer Loren Moron equalized towards the end of the first half, but Luuk de Jong reestablished Sevilla's lead and they survived waves of late pressure to shorten the win, leading to fierce Lopetegui celebrations on the sidelines.
In Ligue 1 Dimitri Payet met twice as Marseilles won 2-1 against Lyon despite the dismissal of Álvaro González in the second half.
Lyon said the team bus had been attacked on the way to the stadium in Marseille. The club published photos of several broken windows and tweeted that the security of the players despite earlier threats against them was not sufficiently guaranteed. The president of Lyon, Jean-Michel Aulas, said five objects hit the bus.
Payet scored two goals for Marseille at half-time, first with a penalty and then with a clinical result, when he was involved three times in a quick counterattack. The second half was postponed for about five minutes as thick fog rose at the Stade Velodrome, but Moussa Dembélé retired after a mistake by González, who then showed a straight red card for a professional foul on former Celtic striker.
But the ten men that Martin Terrier held in the 90th minute, flashed millimeter wide and Jason Denayer header was easy to save.
