Agger's future has been uncertain for much of the summer, and with Liverpool spending even more on defenders, the Dane's time at Anfield may be up.
Liverpool defender Daniel Agger has had his future under the spotlight ever since the final whistle was blown on the final day of the season against Newcastle United.
The competition for places in the centre-back positions was fierce last season as Agger was in direct competition with Mamadou Sakho for his place in the side.
But there have been quotes from Agger suggesting he wasn't happy playing second fiddle to the Frenchman, and combine that with reports that Liverpool are open to selling their vice-captain means the Dane is edging closer to the Anfield exit door.
In addition, the signing of Dejan Lovren from Southampton has also made competition for places all the more fierce.
Barcelona have been strongly linked with a £12 million deal for Agger, but now his old club Brondby - where the Reds bought the defender from for around £5 million in 2006 - appear to be interested in signing the defender.
"We will work really, really hard to secure Daniel but as he has also said, when he was here with Liverpool, the timing has to be right.
"So let us hope we can tie up the loose ends. When that is, time will tell but we will go a long way to get him back because it will show where we set the bar. It will show that we have ambitions and will make a lot of fans happy.
"We will do everything in our power but it is clear that we also need to be responsible and we need to do what is right at the right time.
"But to answer the question, yes, we will do everything that we can, if and when the possibility arises, and see if we can tie up the loose ends."
There is no doubt that Brondby would have an emotional pull for Agger - who recently captained Liverpool during a 2-1 pre-season friendly defeat against the Danish side. But if Barcelona are interested, it could be the more attractive option in terms of profile and chance to win major honours.
It seems that interest is building in Agger, and that his time at Anfield may well be coming to an end.
Would Liverpool be right to sell Agger?
