Lautaro Martinez scored to give Inter Milan an important 1-0 win at Atalanta on Sunday, sending his side into the New Year at the top of Serie A, Reuters reported. 

Inter lead a tightly contested league table on 36 points, one clear of city rivals AC Milan and two ahead of Napoli.

Marcus Thuram appeared to have fired Inter into the lead just before the interval, but the goal was ruled out after an offside by Martinez in the build-up, according to Reuters.
