Inter Milan secured a dominant 4-0 victory over Red Star Belgrade in their first Champions League match of the season, bolstered by a stunning free-kick from Hakan Calhanoglu, a goal from Marko Arnautovic, and a penalty converted by Mehdi Taremi, who also assisted two goals. This win allowed Inter to move into the top eight of the new league phase, accumulating four points after a previous goalless draw against Manchester City. Captain Lautaro Martinez, who scored as a substitute, matched a club milestone with his 13th Champions League goal. Red Star's coach lamented defensive errors that led to their second consecutive loss in the competition. The match took place amidst police investigations into the clubs' ultras, highlighting ongoing issues of crime related to matchday operations. Inter's next fixture is against Young Boys, while Red Star will face Monaco.
