The centre-back wants the Stadio San Paolo outfit to do more despite maintaining their unbeaten streak in the elite European tournament this season
Following Tuesday's 1-1 draw against PSG, Napoli defender Kalidou Koulibaly has called on his teammates to keep improving and remain focus to secure passage to the next round of the Uefa Champions League.
Juan Bernat's goal at the stroke of half-time gave the Parisians the lead but Lorenzo Insigne's equaliser in the 62nd minute ensured both teams shared the spoils at Stadio San Paolo.
The result moved the Serie A outfit who are yet to lose a match in the competition to the summit of the Group C standings with six points from four outings.
