Liverpool are said to be willing to listen to listen to offers for defender Daniel Agger in order to raise funds for potential new signings.
Sky Sports believes that Liverpool boss Brendan Rodgers may be prepared to cash-in on the defender who has already been the subject of two offers from Premier League champions Manchester City.
The Reds have turned down both of the offers but it seems City boss Roberto Mancini is keen to land Agger and will now prepare a third offer which he hopes will be accepted.
There have also been suggestions that Agger is on the radar of Spanish giants Barcelona as new manager Tito Vilanova is aware that they need cover at the heart of their defence, having been forced to play Javier Mascherano in that position regularly last season.
The Denmark international is believed to have held talks about a new contract with the club but it seems these have stalled and there is growing belief that he could now be sold.
Many pointed to the fact that Agger had been left out of the Liverpool squad that played FC Gomel in the Europa League qualifying game last week, but Rodgers has already stated that it was due to concerns over his fitness.
"We have a behind closed doors game for him this weekend to help his match fitness," Rodgers told the club's official website last week.
"Daniel is fit, but we have to make sure his physical condition is up to speed. He wasn't going to play and as that was the case, I wanted him to use that time to work on his physical condition."
However, Sky Sports understands that should a club meet the valuation of £20million then Rodgers may well consider selling and using the money to bring in reinforcements.
They believe that Rodgers has already identified a number of targets should Manchester City or Barcelona meet their demands.
The Reds do have options at the back with Martin Skrtel, Jamie Carragher and Sebastian Coates, while Martin Kelly can also operate in the centre as he has done successfully for the England Under-21 side.
