Spain beat Germany 1-0 to win Euro 2008, but what price are they to go on and become World Champions in South Africa in 2010?

Daniel Alves says he is determined to repay the faith invested in him by Barcelona after completing his move from Sevilla.

Following his 29m move to Camp Nou, the 25-year-old becomes the world’s most expensive right-back, and Alves is relishing the chance to play for Pep Guardiola’s side.

“It is a very important challenge in my life and my career,” Alves told the club’s official website.

“I am hungry to start playing and the sooner the better so I can show that they did not make a mistake with me.

“I am very happy to be living this dream. Not just my dream, but that of so many others that would like to be in my place right now.

“It is a wonderful reward for all the work I have done until now.

“It is a switch from a great club to one that is the same or even better. It is a cause for joy and satisfaction to know that Barca put their interest in me and for me to be able to form part of this new project.

“Barcelona want to return to be the side they were two years ago (when they won a second consecutive Primera Liga title and the European Cup) and I am honoured they have come for me to form a part of this project.”

Barcelona said they had paid €29m with a further €6m dependent on appearances and results, for the Brazilian international. However, the club believe it is money well spent.

“We have signed the best player in his position in the world. He is a full back who likes to attack and offers a great all-round contribution,” Barca sports director Txiki Begiristain told a news conference.
