According to Tuttosport, Dimarco will miss the trip to Madrid with Inter Milan due to a minor knee sprain, and Carlos Augusto will replace him in the starting lineup.

Dimarco was substituted early in the league match against Napoli because of a minor knee sprain. Inter Milan will travel away to face Real Madrid, who were previously coached by Mourinho, in their Champions League debut. Dimarco trained alone in the pre-match session that morning, with a clearly visible bandage around his knee. To avoid risks, the coaching staff chose a cautious approach and left him in Milan to continue receiving treatment. Carlos Augusto will start on the left side.
Chivu's confirmed selections
For the match at the Bernabeu, Chivu has decided to bring Lautaro and Thuram back into the starting lineup. In midfield, Calhanoglu is expected to return, while Zielinski and Jones will compete for one position. On the right side, Luis Enrique and Diouf will compete for a starting spot, replacing the injured Spencer.
In defense, Pavard and Stones are both expected to feature. Stones will also compete with Akanji for a center-back position, hoping to partner with Bisseck, who has a confirmed starting role.
