The defender, on-loan from Valencia, was unveiled in front of 1,000 fans at the Nou Camp yesterday.
The Colombia international said, “I'd like to thank the club for giving the opportunity to come here. I feel like God has opened the biggest door there is in football. My family is very happy and that's the most important thing. I'm going to give everything so that the coach will be able to count on me soon.
“I'm so happy to be able to wear this shirt. I've always wanted to play attractive football. I am an honourable person and I hope I can contribute to the team and help to reach the club's objectives."
