Afterwards, Allegri made a substitution, Bonera came on and Thiago Silva was carried off by a stretcher. The medical staff even put his stretcher on a simple cart and fixed his body in order to be more stable. All signs showed that Thiago Silva had suffered from a serious injury. However, the diagnosis after the game still made people sigh with relief. Chief team doctor Melaga said: "Thiago Silva's ankle was slightly sprained, we are very optimistic, but it is still too early to say whether he can play in the Champions League match against Real Madrid on Tuesday." Originally, it was thought that he would be out for at least a month, but now it seems that he might even play in next week's Champions League, AC Milan fans can breathe a sigh of relief. In fact, after Thiago Silva went off, AC Milan's defense was quite worrying. Not long after he left, AC Milan conceded a goal. Although that goal had little to do with the center-backs, the team was indeed not as confident in defense as before. Bonera, who replaced him, was decent in foot defense, but couldn't win the ball in the air. During the 73rd minute of the opponent's counter-attack, Bonera failed to clear the ball in one-on-one defense, giving the opponent an opportunity to knock back to an unmarked area outside the penalty area for a far shot. However, Fernandez's shot grazed the post. If Thiago Silva can't play in the match against Real Madrid, it will be really troublesome. Bonera is currently the first substitute, but there is obviously a gap in ability. Moreover, Bonera has consistently performed poorly in the Champions League, from the meaningless red card against Anderlecht to the poor performance after replacing Maldini at Old Trafford, all indicating that Bonera's psychological quality is average. But compared to him, Greek Papastathopoulos is even less experienced. Plus, the mistake he made in the previous match against Cesena makes Allegri reluctant to use him again. And Yepes hasn't played a single minute this season, and his characteristics are close to Nesta, so the combination may not be reasonable. From the current situation, even if Thiago Silva hasn't fully recovered, as long as he's about 80% fit, he will likely grit his teeth and appear on the field at Bernabeu. "If it weren't for Thiago Silva's injury, this game would have been more enjoyable," said Galliani after the 3-1 victory over Chievo. It can be seen that Thiago Silva's injury still made the senior management of AC Milan quite worried. At the 16th minute of the second half, after Thiago Silva fell down in pain after a tackle on the wing, his expression was painful, and both Galliani in the stands and Allegri on the bench looked grim.
