"I want to win Serie A, and then also the Champions League."
"Wearing the No.4 shirt is certainly a source of pride but also a responsibility," he continued. "I hope to do my best to make the fans as happy as he did.
"It makes no difference where I play; the important thing is to play. If I must choose, I do like central defence the most, but it does not matter," concluded Caceres.
