Barcelona have reportedly made a €60 million offer to sign Ajax defender Matthijs de Ligt and are hoping to have the deal completed inside a month.
According to Sport, Barca have put forward that initial offer, which will also include add-ons, along with a five-year deal for the player.
"Sources close to the negotiation say the transfer is on track and the club are very optimistic" of securing his signature ahead of European rivals Juventus, Paris Saint-Germain and Bayern Munich.
Sport's Lluis Miguelsanz also reported on a potential collaborative relationship between Barca and Ajax, one that will give the Catalan club "priority" over the Dutch club's talented youngsters and in turn will see the Blaugrana's younger players head in the opposite direction on loan.
