Dos Santos official at Spurs

Tottenham Hotspur announced Tuesday the signing of teenage Mexico forward Giovani dos Santos from Barcelona.

The 19-year-old has now passed a medical and agreed terms with the north London club in a five-year deal worth an initial 4.7 million pounds (9.4 million USD).

Giovani told the the Premier League club's website: "It is a dream for me to come to a big club like Spurs. I've come here to further explore my qualities and give my all for my new team."

Tottenham finished 11th in the Premier League season but qualified for European football after winning the League Cup.

Spurs may have to pay Barcelona as much as 8.6 million pounds (17.2 million dollares) for Giovani, depending upon appearances. But Tottenham manager Juande Ramos believes it will be money well spent.

"If Giovani progresses as we hope, he will be a terrific player," said Ramos, who as a Spaniard shouldn't have any problems talking to Giovani.

"This is a young player with a lot of potential, who I have watched for some time. For us it is an exciting signing because he has excellent quality, he operates well in different positions and, above all, is technically excellent."

Barcelona have retained the right to 20 percent of any fee should the teenager move on from Spurs in the next two years and they will get 10 percent if he is sold later in his contract.

Tottenham have a reputation as an under-achieving side but Giovani added: "It's a dream to come to a big club like Spurs. I came here because of the passion of the fans, the size of the club and I can see us growing in the future."

Giovani, who in 2005 helped Mexico win the FIFA U-17 World Cup, spent five years coming up through the Barcelona youth system and scored a hat-trick in the final league game of the season as Barcelona beat Murcia 5-3.
