Barcelona are ready to test Liverpool's resolve for defender Dan Agger.
The Daily Express says the Catalan giants are looking to make reinforcements with Eric Abidal recently returning to action after undergoing a liver transplant and Carles Puyol a long-term absentee.
Agger has been an ever present feature for club and country this season, clocking up 43 appearances.
Reports from Spain have surfaced that Javier Mascherano, who knows Agger during his time at Anfield, has endorsed his signing.
