Daniel Alves is determined to prove Barcelona have not made a mistake in spending big money to sign him from Sevilla.
The Brazilian full-back has been presented as a Barca player after agreeing a deal to move to Camp Nou last month.
Barca have stumped up a sum in the region of £23.5million to prise Alves away from Sevilla, and the 25-year-old 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."
