Napoli defender Kalidou Koulibaly has called for focus after their comfortable win over Cagliari.

Napoli maintained their superb start to the season with a 3-0 victory.

Koulibaly stated: "We go game by game.

“We've done well in these first seven matches and we want to continue like that.

“Today we played well despite the early kick-off. We kept going until the end, got the goals and we are happy.

“We want to keep going like this. Seven games are nothing because the League is a marathon.

“All matches are different, we need to go game by game and then see where we are in March or April."
