Daniel Agger's agent has confirmed an approach for his client from Spanish champions Barcelona. The Danish international could be on the verge of a big money move away from Anfield.

"We are aware that Barcelona have made an offer for Daniel that Liverpool have rejected. Daniel has a contract with Liverpool for three years and it would be up to the clubs to agree a fee for his transfer in order for that to change," Per Steffensen explained.

The Guardian believes Nou Camp chiefs offered Liverpool £14.6m for the 28-year-old. They are expected to return with a bigger offer.

Liverpool are understandably reluctant to lose the centre-back, given veteran Jamie Carragher retired earlier this summer. The ex-England man's absence leaves only Agger, Slovakian international Martin Skrtel and new signing Kolo Toure as first choice central defenders. And with the transfer window drawing to a close, time is short for Brendan Rodgers to sign a suitable replacement.

However, the Catalans' need for a top quality centre-back is pressing. The lack of cover in central positions has been Achilles Heel for some time now and an aging Carlos Puyol (the club captain is now 35 years old) means a new central defender is priority.

New Barcelona manager Gerardo Martino has reportedly also considered Chelsea defender David Luiz and several reports linking him with a big money move for the Brazilian international have surfaced. The most recent was the Mail's, stating that an offer £34.5m was made for the 26-year-old. However, Chelsea boss Jose Mourinho is very clear that he expects Luiz to stay in west London this season.

Rodgers, though, is clear that he expects Agger, the club's vice-captain, to stay with the Reds. The former Swansea City boss said he trusted his star defender.

"This is all about loyalty. He's obviously a world-class defender. Daniel is very committed to Liverpool; he's one of the players that have really impressed me. If we're talking about loyalty, he was one of the first players that I spoke to when I became the manager," the Northern Irishman said.

"At the time, there were a number of big clubs looking to sign Daniel. But he gave me his word that for as long as I wanted him to be at Liverpool, he would be at Liverpool. He has never swayed from that," he added.
