Barcelona have reportedly identified Liverpool centre-back Daniel Agger as a key summer acquisition in the Primera Division champions' pursuit of defensive reinforcements.
The Catalan giants are keen to recruit at least one more centre-back before the transfer deadline and, according to El Mundo Deportivo, have placed Agger at the summit of their list of targets.
Eric Abidal's departure and the advancing years of Carles Puyol have led Barcelona to enter the market for a central defender, with Thiago Silva of Paris Saint-Germain the club's initial top choice.
Thiago has, however, maintained his intention to remain at the Parc des Princes, and now Barcelona will reportedly ramp up their bid to bring Agger from Anfield to the Camp Nou.
Agger improved his reputation as a ball-playing centre-back under Liverpool manager Brendan Rodgers last season, enjoying arguably his most impressive season during six years on Merseyside.
Liverpool, then, would be loath to allow Agger to leave the club even after Rodgers signed Kolo Toure from Manchester City to provide him with a greater breadth of options at the back.
Agger has made 209 appearances for Liverpool since signing for the Reds fromm Brondby for a fee of £6 million during the summer transfer window of 2005.
