Tottenham are to set to sign Argentinian forward Erik Lamela from Roma after the Serie A club accepted a bid of 30million euros.

The 21-year-old has scored 19 league goals in two seasons with the Italian capital club and, should his move to White Hart Lane go through, he will help fill the gap left by Gareth Bale should he complete a world-record £86m move to Real Madrid.

A statement published on Roma's official website read: "Roma announce they have signed a contract with Tottenham for the outright sale of the playing rights of Erik Lamela, in exchange for 30million euros. The agreement also includes the obligation to pay 5million euros in bonuses related to the achievements of the player and the English club."

Lamela, who has been capped three times for Argentina, arrived at the Stadio Olimpico from River Plate in August 2011 and made 29 appearances, scoring four goals, in his first year in Italy.

A run of seven goals in six games at the start of the 2012-13 season saw him become an essential part of Roma's forward line, even though the campaign ended with a disappointing sixth-place finish and defeat to city rivals Lazio in the Coppa Italia final.

With Wales winger Bale absent from training as a dispute over a move to Real Madrid rumbles on, and with Spurs missing out on Willian following the Brazilian playmaker's decision to join Chelsea instead, the pacey Lamela offers a viable and talented alternative to both players.

The continued spending in north London indicates Bale's £86m move to the Spanish capital is all but ratified as Lamela joins Roberto Soldado, Paulinho, Nacer Chadli and Etienne Capoue in Andre Villas-Boas' new-look squad.

Lamela's place behind Francesco Totti in the Giallorossi team, meanwhile, will be filled by Serbian forward Adem Ljajic, who has today completed an 11million euro move from Fiorentina.

Roma also announced that Serbia forward Adem Ljajic has signed a four-year deal with the club after joining from Fiorentina for 11 million euros. ($14.5 million). Roma added that the transfer fee could reach 15 million euros ($20 million) with bonuses.

The 21-year-old Ljajic joined Fiorentina in January 2010 and scored 15 goals in 78 Serie A appearances for the Tuscan club.

In May 2012, Ljajic sarcastically applauded coach Delio Rossi for substituting him and Rossi punched him. Rossi was then fired.

Fiorentina signed 19-year-old Croatian forward Ante Rebic from RNK Split as a replacement for Ljajic.

Both Roma and Fiorentina won their Serie A openers last weekend.
