In the summer window this year, Chelsea waived Thiago Silva, and the Blues defender Zuma also talked about his sister-in-law in an interview with the club's official website.
Zuma said: “When Thiago Silva walks into Cobham’s door, he will give advice to the players around him. He is really good at getting along with people. Good leadership skills."
"Everyone welcomes Thiago to join the team. We are all very happy that he can work with us at Chelsea."
"I'm very happy to work with Thiago. But I don't think I'm the only person who is happy. In fact, many people at Chelsea feel the same way. We are all happy to play with him and learn from him. He is a top player with a lot of experience. He has won many championships. He also participated in the Champions League final last season."
"For me, he has all the qualities. He is very calm with the ball, he defends well, and he has a great sense of position. I am very happy that he came to Chelsea and I am very happy to learn from him."
