Calhanoglu secures Inter's perfect start; Como stun Napoli

Inter Milan extended their perfect Serie A campaign with a hard-fought 1-0 win over Cagliari on Sunday, with midfielder Hakan Calhanoglu's goal securing three crucial points for the defending champions. The Turkish international's decisive strike proved enough to overcome a resilient Cagliari side in what proved to be a tightly contested affair at the San Siro.

The Milan club's flawless start to the season keeps them firmly in contention atop the Serie A standings, though the narrow margin of victory highlighted their opponents' determination to frustrate the league leaders throughout the encounter.

Elsewhere, Como produced an eye-catching performance to topple Napoli 2-1 in a stunning upset that overshadowed the occasion of Allegri's first home match in charge of the southern club. The visiting side's aggressive approach caught Napoli off guard, with the Serie A heavyweights unable to mount an effective second-half comeback despite their efforts.

Allegri's inaugural home fixture thus ended in disappointment, marking a difficult start to his tenure as Como looks to establish itself as a competitive force in Italian football's top division.
