Barca interested in Koulibaly

Barcelona are interested in Napoli defender Kalidou Koulibaly.

La Gazzetta dello Sport says Barca are eager to make a new centre-half signing this summer.

Barca have asked Juventus for Matthijs de Ligt, but were turned off by his price.

Instead, they're turning to Koulibaly, who has a deal to 2023.

Napoli were demanding €80m for the Senegal international 18 months ago, though would now be willing to part with the stopper for €40m later this year.
