Christian Pulisic's goal gave AC Milan a 1-0 win over city rivals Inter Milan at the San Siro on Sunday with Mike Maignan saving Hakan Calhanoglu's penalty to deny the hosts an equalizer, Reuters reported.

Inter's three-match winning run had brought them to the top of the standings, but there is little room for error in this season's Scudetto battle, where AS Roma hold pole position after a 3-1 win at Cremonese and Milan are now on their shoulders.

Milan moved up to second spot on 25 points, two behind Roma, and level with defending champions Napoli while Inter, who could have returned to the summit with a win, slipped to fourth place on 24 points alongside Bologna, according to Reuters.
