Barcelona are ready to launch a bid for Napoli defender Kalidou Koulibaly.

Barca international scout Ariedo Braida was at San Paolo on Wednesday night to see Napoli's Champions League win over Liverpool.

Mundo Deportivo says the Italian was primarily in the stands to see Koulibaly in action.

Braida has long been a fan of Koulibaily and explored bringing him to Barca when he first arrived from AC Milan.

However, the stumbling block will be Napoli's asking price with president Aurelio de Laurentiis refusing to consider any offer less than €65m.
