Silva opted to leave Granada at the end of 2020/21, after five seasons with the Andalucians, including top-flight promotion in 2019, despite being offered a contract extension.
The 27-year-old has now signed a five-year contract at the Estadio Benito Villamarin to join boss Manuel Pellegrini.

Los Verdiblancos secured a place in the 2021/22 Europa League at the back end of last season and Pellegrini wants to reinforce his squad options.
However, with Emerson heading in the opposite direction, as part of the Real Betis’ co-ownership deal with the Catalans, Pellegrini has brought in a new right back.
Senegalese international Youssouf Sabaly has joined on a free transfer following his own release from Ligue 1 side Bordeaux.
