3) Daniel Agger
Recently linked with a move to Barcelona, it may be that Liverpool will decide to cash in on the Danish international, who was not quite at his best for much of last season. The 29-year-old has been a terrific servant to the club since joining all the way back in 2006, but there is no guarantee of him being first choice in defence now. It remains to be seen if Lovren has in fact been signed to replace Agger, or to play alongside him, but it leaves Brendan Rodgers with some thinking to do as the new season approaches.
