Lucas Silva will wear the number 16 shirt for Real Madrid.
The Brazilian, who completed his move to the Bernabeu from Cruzeiro on Saturday, was officially presented as a Real Madrid player on Monday afternoon.
The 21-year-old has taken the number 16 shirt which had been held by Casemiro, who is currently on loan at Porto.
During his presentation to the Bernabeu faithful, Silva ran through the usual repertoire of kick-ups and subtle skills.
The midfielder also completed his medical earlier on Monday.
