Tottenham's summer spending spree passed the £90million mark when they completed the signing of Erik Lamela from Roma.
Vlad Chiriches became the club's fifth summer purchase on Friday morning when he completed his £8.5million move from Steaua Bucharest and four hours later, the north London club confirmed that they had signed 21-year-old Lamela for a fee thought to be around £25.8million.
"We are delighted to announce that we've reached agreement with AS Roma for the transfer of Erik Lamela," Spurs said on their Twitter feed.
Lamela, who has three Argentina caps, moved to Roma from River Plate two years ago and he quickly become recognised as one of the hottest properties in Europe.
Lamela scored 21 goals in 67 appearances for the Italian club, where he played in a number of positions across midfield.
Lamela arrived in London on Wednesday night, but Tottenham would not comment on the player's potential signing for fear that another club may snatch the midfielder from under their noses with an 11th hour bid.
Tottenham have now spent approximately £92.8million in this transfer window following the signings of Lamela, Chiriches, Roberto Soldado, Paulinho, Etienne Capoue and Nacer Chadli.
Spurs are also close to signing midfielder Christian Eriksen from Ajax.
Should the deal for the Dane go through, it is likely to pave the way for Gareth Bale to complete his world-record move to Real Madrid.
