Ahead of tonight's Champions League quarterfinal first-leg tonight against Bayern Munich at the Santiago Bernabeu, the Brazil attack conceded he is happier under Arbeloa than the coach's predecessor Xabi Alonso.
He said, "I've had a connection with Arbeloa's playing style, just like I did with (Carlo) Ancelotti. I've always given everything for the team.
"I think I've never gone so long without scoring goals, like when I was young and didn't have much focus, but I've learned from that last bad spell, and good players always turn things around."
Asked why he didn't post a farewell thank-you to social media for Xabi after his dismissal, Vini Jr added: "I played a lot of games, but few minutes.
"Every coach has their methods, and I didn't connect with him the way he wanted. But I see it as a learning experience, and I hope I can continue with Arbeloa. I have a wonderful connection with this coach, and he has always shown me his confidence."
