Inter Milan enters the fray after a highly competent five-match unbeaten pre-season run, though their squad looks fundamentally altered. The defending champions lost Denzel Dumfries to Real Madrid, alongside the departures of defensive veterans Francesco Acerbi and Stefan de Vrij. To patch these critical areas, management secured Djed Spence and John Stones, directly fortifying the right flank and central defense. Targeting a versatile ball-player like Curtis Jones aligns perfectly with their trademark 3-5-2 system, especially since Manuel Akanji and Filip Stankovic have already arrived to thicken the squad depth. This deep bench is not a luxury but a necessity, as navigating Serie A, the Coppa Italia, and the Champions League simultaneously will severely test their physical endurance over the coming months.

Across town, AC Milan is actively wrestling with defensive cohesion. Their warm-up fixtures yielded a mixed return of one win, two draws, and a concerning 3-0 defeat to Chelsea that laid bare structural gaps at the back. A subsequent 4-2 victory showcased their undeniable attacking bite, heavily aided by the arrival of Portuguese forward Gonçalo Ramos and veteran Luka Modric's pristine midfield distribution. Real Madrid academy product Mario Gila brings modern passing ability out from the backline, and ongoing rumors link them to Belgian winger Diego Moreira. However, integrating the defense quickly remains their most pressing assignment if they intend to challenge their local rivals.

Juventus, rather than hunting for a singular marquee signing, opted for aggressive, widespread attacking investments. Committing over €40 million each for Loïs Openda and Randal Kolo Muani, alongside a €32 million acquisition of 18-year-old Bosnian winger Kerim Alajbegovic, signals a complete offensive overhaul. At the opposite end of the pitch, Colombian center-half Jhon Lucumí and on-loan Tottenham goalkeeper Guglielmo Vicario provide necessary reinforcement. Despite this massive capital injection, a 2-1 pre-season loss to Inter suggests they might still sit a step behind the reigning champions, even if they comfortably dispatched their own youth squad 2-0 shortly after.

Further down the table, tactical shifts continue. Napoli’s strategy centers on replacing Romelu Lukaku with Rasmus Højlund and winger Alisson Santos, while retaining an aging Kevin De Bruyne. A 6-2 pre-season thrashing hints at sharp finishing, but consistently cracking the top three looks difficult given the midfield's shifting dynamic. Meanwhile, Atalanta has shrewdly converted winger Nicola Zalewski into a central midfielder, a tactical tweak that has looked highly effective in warm-up matches, marking them as serious contenders for a top-four finish as the season begins.
