The 22-year-old joined Liverpool from Brondby in 2006.
Agger’s agent Per Steffensen told Danish paper Politiken: “My comment is that I don’t have one.
“However it is normal that several major clubs should be interested in a 22-year-old who has improved as much as Daniel has during the last season.”
Agger’s current contract at Anfield expires in 2010.
