Daniel Agger's representatives have indicated he would be open to a move to Barcelona if Liverpool can agree a fee for the defender's release, the Daily Mail reports.

Despite Liverpool denying they had received an offer for Agger, it is understood Barcelona have made a £15million bid to secure the Denmark international, who is Liverpool's vice captain.

Brendan Rodgers is adamant Liverpool will retain Agger but that may change today as Barcelona wait to see if David Luiz will push to leave Chelsea. 

Agger is a significantly cheaper option than Luiz and a new bid will give Rodgers a problem. 

Agger signed a new contract last season but his agent, Per Steffensen said: 'We are aware that Barcelona have made an offer for Daniel that Liverpool have rejected. 

'Daniel has a contract with Liverpool for the next three years and it would be up to the clubs to agree a fee for his transfer in order for that to change.'

Liverpool are monitoring developments with Paris St Germain's Mamadou Sakho and have made a £5million offer for Granada left-back Guilherme Siquiera.
