(CNN) -- English club Tottenham have completed the signing of promising young Mexico midfielder Giovani dos Santos from Barcelona, the Spanish club announced on Friday.
Giovani dos Santos has swapped the Nou Camp for a move to Tottenham's White Hart Lane.
The 19-year-old has signed a five-year contract for a $9 million fee, which could rise to $17 million depending on appearances.
Barcelona, who signed the player in 2002, will also receive 20 percent of any future transfer fee from Tottenham within the next two years.
The Premier League club clinched their second high-profile capture of the post-season following the $30 million deal to bring young Croatia playmaker Luca Modric from Dinamo Zagreb.
"FC Barcelona and Tottenham Hotspur have come to an agreement for the transfer of Giovani Dos Santos to the English club," the Catalans said in a statement.
"The Mexican will sign for the club managed by Juande Ramos until June 30 2013 for a fee of six million euros plus another five million depending on the player's appearances for the London club during his five-year contract.
"FC Barcelona also maintain 20% of the financial rights to any possible transfer of the player during his first two years of contract and 10% on any transfer from his new club."
The transfer was widely expected to happen next week, with the father of Dos Santos -- former Brazil international Zizinho -- telling the English media that a deal was imminent.
Ramos, who knew Dos Santos well from his time managing Spanish club Sevilla, has now added two highly-creative midfielders to a squad that last season often seemed lacking in imagination outside of strikers Dimitar Berbatov and Robbie Keane.
Dos Santos, who made his Champions League debut last season under the departed Frank Rijkaard, can again look forward to European football as the London club have qualified for the UEFA Cup.
He made his first-team debut last season, scoring a hat trick in the final league game of the campaign against Murcia.
Dos Santos was a member of the Mexico Under-17 team that won the 2005 World Cup and also played at U20 level before making his senior debut under former coach Hugo Sanchez in September last year.
Sanchez was replaced by former Manchester City boss Sven Goran Eriksson earlier this week.
