Inter Milan secured a crucial 1-0 victory over Atalanta, with Lautaro Martinez scoring the decisive goal in the 65th minute. The win propelled Inter to the top of Serie A heading into the New Year, holding a one-point lead over AC Milan and a two-point advantage over Napoli. Despite several disallowed goals and missed opportunities for both sides, including a spectacular save by Inter goalkeeper Yann Sommer, Martinez's strike proved sufficient. Atalanta's Pio Esposito provided the assist after capitalizing on a defensive error.
