The former Sao Paulo wonderkid was signed in the summer.
"I think the Brazilian player at Chelsea who has helped me the most is David Luiz. We are here in his house, with Julio [Lucas and David Luiz's agent]. Alex and Ramires are very good guys too, they have helped me in this last week as I was training with them. We are making good friendships," he told Sambafoot.
"Only with Alex (did I know before). I met him in 2009, here in London. David Luiz and Ramires I didn't know before."
