AC Milan surged to the top of Serie A as Olivier Giroud gave them a crucial 1-0 victory over fellow challengers Napoli.
The big French striker stuck out a boot to steer in Davide Calabria’s low, driven cross early in the second half.
Napoli pushed hard in search of a route back into the game but could not find a way past a stubborn visitors defence.
The win takes Milan top on 60 points, two points better than fierce rivals Inter Milan and three ahead of Napoli.
Nigeria’s Victor Osimhen saw a couple of shots saved by Mike Maignan and substitute Adam Ounas flashed an effort wide as the home side desperately sought parity.
Milan felt they should have had a penalty for a foul by Kalidou Koulibaly on Ismael Bennacer but the referee waved away the shouts, as he did at the other end for Fikayo Tomori’s challenge on Osimhen.
