Zlatan Ibrahimovic scored twice to bring his tally to 10 league goals this season before limping off with a muscular strain as AC Milan stayed top in Serie A on Sunday with a 3-1 win at ten-man Napoli.
Milan move back two points ahead of Sassuolo — 2-0 winners earlier at Hellas Verona — with Roma third after Henrikh Mkhitaryan scored twice in a dominant 3-0 win over Parma.
Ibrahimovic continued his fine form, heading in a Theo Hernandez cross after 20 minutes, sending in the second with his knee nine minutes after the break.
But the 39-year-old pulled up clutching his left hamstring and was substituted after 79 minutes.
