Tottenham remain in talks with Atalanta over a deal for centre-back Cristian Romero.
Spurs have made an offer of at least £34m (€40m) for the Argentina international but that was over a week ago and still no fee has been agreed with the Italian club.
According to Sky in Italy, Atalanta want to ensure they have a replacement through the door before any further progress can be made, with interest in Juventus' Merih Demiral, Lazio's Luiz Felipe and Bologna's Takehiro Tomiyasu, whom Spurs have also been trying to sign.
Personal terms with the 23-year-old are not expected to be a problem if the two clubs can agree, with Tottenham prepared to give Romero a five-year deal plus an option of a further year.
Tottenham's new managing director of football Fabio Paratici has intensified discussions over Romero, who also attracted interest from Manchester United earlier this summer, after already sealing a loan deal for Atalanta goalkeeper Pierluigi Gollini.
The 26-year-old Italian was Spurs' first signing of the summer under new head coach Nuno Espirito Santo and is expected to challenge Hugo Lloris for the number one spot.
Spurs also have an option to buy Gollini on a permanent deal for £13m if he plays a certain number of games in the upcoming season, according to Sky in Italy.
Tottenham have also signed winger Bryan Gil from Sevilla, with Erik Lamela joining the Spanish side in a swap-plus-cash deal.
Spurs will also pay Sevilla £21.6m for Gil, according to Sky in Italy.
The 20-year-old has signed a five-year contract with Tottenham, while Lamela has joined Sevilla on a three-year deal.
