Rangers have confirmed that Bruno Alves has become boss Pedro Caixinha's first summer signing after agreeing a two-year deal.
The 35-year-old Portugal defender arrives from Serie A club Cagliari, who confirmed his departure earlier.
The former Porto, Zenit St Petersburg and Fenerbahce centre-back has been capped 89 times and was a member of Portugal's Euro 2016-winning squad.
Alves told RangersTV: "I am very happy to join the club and I will do my best to win.
"The main reason that I come here, I have this feeling and desire to win and to move here will bring this back to me and my career.
"In almost all the clubs I have played for, I win and I expect to win here, for the fans, for the club and I think I can do this here.
"It is going to be an amazing journey, I am sure about that."
Rangers boss Pedro Caixinha claims new recruit Bruno Alves has all the attributes to be a success at Ibrox.
Caixinha told the club's official website: "In my opinion all teams need to be built and organised from the back and Bruno is a very talented and experienced player.
"He is also really mature and a leader with a strong character, so I'm very happy that he has signed a two-year deal with us at the beginning of this new project and this new cycle we want to start with Rangers.
"I'm also very happy of course that he is my first signing.
"What is important is that he is a winner with a winning mentality and that is something we all want, to put the club on a winning track again.
"Bruno will be a leader in the dressing room and he will demand a lot from himself and others in the squad, both on the pitch and in our training sessions.
"The players we are trying to bring to Rangers, we want them to have that character, that experience and that maturity, but also that winning mentality.
"Bruno will definitely be one player who is going to help with that."
