Tottenham have completed the signing of defender Cristian Romero for a reported fee of £47million.

The Argentina international has put pen to paper on a reported five-year contract with the north London club.

The 23-year-old becomes Tottenham's third signing under Nuno Espirito Santo following the arrival of winger Bryan Gil from Sevilla and the loan acquisition of Atalanta goalkeeper Pierluigi Gollini, whom Romero played alongside in 2020-21.

Romero is also the second-most expensive transfer in Spurs' history after Tanguy Ndombele's £53.8m switch from Lyon in 2019.

After beginning his career with spells at Belgrano and Genoa, the centre-half failed to make a competitive appearance during his two-year stint with Juventus, spending the entire time out on loan.

Atalanta signed him on loan with a purchase option in September 2020 and Romero went on to play 42 times in all competitions last season as the Bergamo club recorded a third-place finish in Serie A and reached the Coppa Italia final.

Atalanta triggered their purchase option on Romero before then selling him on to Spurs.

Romero's performances led to his senior international debut against Chile prior to this year's Copa America, in which he made three appearances and started the final as Argentina beat Brazil to end their 28-year wait for a major trophy.

His arrival provides a much-needed boost to the Tottenham back line, following the departures of Toby Alderweireld and Juan Foyth earlier in the window.

Romero will compete with Davinson Sanchez, Joe Rodon and Eric Dier for a place in the heart of the defence, and could make his debut when Spurs launch their Premier League campaign against reigning champions Manchester City on August 15.
