Inter Milan maintained their 100% record in Serie A with a narrow victory over Chievo thanks to Mauro Icardi's first-half strike.

Argentina international Icardi, 22, slipped the ball under the home keeper after getting on the end of midfielder Geoffrey Kondogbia's floated cross.

Chievo went close with a Valter Birsa free-kick and Lucas Castro's header.

Inter's victory was their fourth in as many games and consolidated their place at the top of the table.

Former Manchester City boss Roberto Mancini returned for a second spell as Inter coach last November and guided the club to eighth place in Serie A but played down title talk after the win.

He said: "It's great to be on top, but what counts is being among the top placed teams in the last month of the season."
