The Brazil fullback is determined to help Barca win the Club World Cup this week.
Alves said: "I came to the right place at the right time.
"I always like joining teams that are under construction. When you join a team that is already mature, it is difficult to find your place and maintain the success.
"We've done a great job, made a very important effort and we managed to make history (winning the Treble).
"Winners do not like losing, even if you've got fifty titles, we were born to win. We work to win."
