Romelu Lukaku scored in his first Milan derby as Inter Milan beat AC Milan 2-0.
Marcelo Brozovic gave Antonio Conte's side the lead with a deflected strike, which was confirmed after a VAR review.
Former Manchester United forward Lukaku headed home his third goal in four Serie A matches from Nicolo Barella's cross.
Inter ‑ who have won all four of their league games this season so far ‑ are now back to the top of the table, above champions Juventus, who beat Verona 2‑1 earlier on Saturday.
Inter last won the Serie A title in 2010 as part of the treble under Jose Mourinho.
In other matches, Leicester beat Tottenham 2-1, Manchester City thrashed Watford 8-0 while Newcastle and Brighton drew nil all.
