Daniel Agger is fondly remembered at Anfield having spent eight and a half years with the club, and the Dane had some memorable moments during his time with Liverpool.
His time at Anfield was not without injury worries, though he managed to score 14 goals from 232 appearances - with most of his best football with the Reds coming under the management of Rafa Benitez - who signed him from Brondby for £5.8 million - but only had the one winners' medal from his time at the club to show for his efforts.

While ending his career at 31-years-old feels very premature, but there are some good memories associated with the Dane - including his only piece of silverware.
Some will remember his crucial goal in the Champions League semi-final against Chelsea in 2007 which brought the Reds back on level terms - with Liverpool eventually progressing to Athens on penalties, while there were a couple of memorable strikes from that left foot of his.
Others will remember a famous clash between Agger and Fernando Torres shortly after the Spaniard had left the club for Chelsea. The first game after the transfer took place was at Stamford Bridge between Chelsea and Liverpool - the Reds won 1-0, and Agger didn't seem to appreciate Torres leaving the club.
Here are five images touching on some of those memories with Liverpool:
