As Ontheminute.com reported yesterday, the Spanish giants are interested in signing Agger.
Benitez told Liverpool’s official website: “The situation is very simple, Daniel Agger is our player and he is not for sale.
“His future is at Anfield and nowhere else. He knows my ideas because we have talked with him and he has a long future with us.
“We do not want to lose our concentration just before we play Manchester City by talking about other things but it is important that people know that Agger is not for sale.”
