The midfielder wants to do well for the Biancocelesti...
"This is my new home, and I am here to do well," the Brazilian told LaLaziosiamonoi.it. "I am very happy to be here at this great club, Lazio.
"I promise to do my utmost, and I want to have a great season - even scoring the winning goal in the derby. Forza Lazio."
Coach Edy Reja believes time will be needed by the player in order to settle in.
"We need to give him time to settle in," Reja said. "He is a player who is very intelligent tactically, and I am sure he will not disappoint.
"He is a person who has his head on his shoulders, and will do well."
