The highly-rated centre-back has admitted his admiration for the Spanish giants.
Manchester City and Barcelona have both been linked with the former Brondby defender.
Agger is quoted as saying by Ekstra Bladet: “Playing for Barcelona would be a huge accomplishment. They have the best team in the world so that is a given.
“But I am very happy here (Liverpool). I feel that I have a good place in the club and that I have a lot of influence on the pitch.”
