Tottenham will sign forward Giovani dos Santos from Barcelona, subject to a medical and agreeing personal terms.

The Mexico international will sign a five-year deal in a move which will cost an initial £4.7m and could rise to £8.6m depending on appearances.

Barcelona have retained the right to 20% of any fee should the 19-year-old move on from Spurs in the first two years of his spell with the club. And they will get 10% of any fee if he is sold later in his contract.

Dos Santos first joined Barcelona in 2002 and came through the youth ranks at the Nou Camp.

He broke into the first-team under former boss Frank Rijkaard last season and made 16 starts in all competitions and came on as a substitute 22 times in the campaign.

Dos Santos also scored a hat-trick in the final league game of the season as Barca beat Murcia 5-3.

The winger, who can also play up front or behind a main striker, helped Mexico to win the World under-17 championship in Peru in 2005.

He is regarded as a promising talent but appears to have been allowed to leave by the Nou Camp oufit as they also have youngsters Lionel Messi and Bojan Krkic in their ranks.

South American football reporter Tim Vickery told BBC Sport: “He is the son of Brazil international Zizinho, but he plays for Mexico - and masterminded the 3-0 win over Brazil in the final of the 2005 World Under-17 Cup.

“He is a slight figure with a terrific burst of acceleration and he has a superb left foot.”
