Italian website Sportitalia, as quoted by the Daily Mail, is reporting that Spurs are ready to make a higher offer for the Argentina international after having failed with an opening bid of £34m plus £8m in add-ons.
The same article states that Tottenham chief Fabio Paratici is negotiating with Atalanta in the hope of striking a deal despite interest from FC Barcelona.
FC Barcelona’s interest in the South American defender has prompted Atalanta to reevaluate their asking price for the 23-year-old this summer.
The report goes on to add that Atalanta are thought to be demanding around £45m for the Copa America winner after FC Barcelona failed with an opening bid for the South American defender.
Sportitalia report that FC Barcelona made an offer of a swap deal but the Serie A side rejected the bid but the Spanish side are expected to return with a fresh bid.
