Kalidou Koulibaly is one of the two top targets for Barcelona in this year's transfer window. Xavi Hernandez is looking out for options to bring in a new centre-back for his squad. Even though Jules Kounde is the top target, his pricetag is too expensive for Barca and thus they have been keeping their eyes on Koulibaly whose term with Napoli will expire at the end of next season. He could be a good prospect during the summer transfer window for Barcelona.
Also, Kalidou Koulibaly has no plans on extending his term with Napoli. So, he will either be a free transfer agent in 2023 or stay back with the club. But Napoli are ready to sell him instead of letting him go for free next year.
