New Barcelona signing Douglas wants to take the best bits of Dani Alves and Cafu's games and become an important first-team member at Camp Nou.
The right-back joined Barca from Sao Paulo this summer for an initial fee of €4 million, potentially rising to €5.5m, and he is determined to give his all in order to succeed at his new club.
"I want to harness the very best aspects of Dani Alves and Cafu," the Brazilian told the official Barcelona website.
"They both have something different to offer and so much quality to their game. I have to learn from both of them if I want to earn my place at Barcelona.
"What I have to do is work hard for when the coach needs me. It is hard to know whether I’m ready or not. I have only just left Brazil and in order to keep adapting to Barca I’m going to have to work on assimilating the group dynamic.
"European football is much faster, but I’ll be ready for this as soon as I can be.
"I’ll listen to everything Luis Enrique can say to make me better. I want to develop my sense of tactics at Barcelona. I like working hard. In football, you earn your chances by working hard in training."
The 24-year-old has signed a contract with Barcelona until June 2019.
