Napoli defender Kalidou Koulibaly has apologised to fans after their defeat to Lecce.

The result ended Napoli's mini revival under coach Rino Gattuso.

"We need to react as a real team," Koulibaly wrote on social media. “Work and score points. Napoli does not deserve this ranking."

Napoli meet Inter Milan in the semi-finals of the Coppa Italia on Wednesday night.
