Barcelona want to significantly reinforce the squad this summer, but it's clear that they don't have that much money available.
Thus, Diario Sport report that the Catalans could try to include players in a possible deal for Kalidou Koulibaly. However, it's not specified what players exactly the club will try to offer.
Barca have been interested in Koulibaly for a while. The defender has only one year left on his contract with Napoli, and this could be their chance to sign him.
This term so far, Koulibaly has made 32 appearances for Gli Azzuri, scoring three goals and providing two assists.
