"The manager wanted me to come here which was important for me. I found him to be a nice man and Rafa was a big influence on me coming to Liverpool," the defender told the club's official website.
"I am looking forward to my first game at Anfield and playing in front of the Liverpool supporters. I can't wait. I have been to Anfield and it is beautiful. I can't wait to see it when it is full of fans."
