Daniel Agger is a centre-back whose ability on the ball allows Liverpool to build from the back.
The Denmark international made his professional breakthrough for Brondby in 2004 and, under the guidance of club captain Per Nielsen, quickly developed into a classy defender with a maturity beyond his years.
In December 2004 he won the Spillerforeningen Talent of the Year award (the Danish equivalent of PFA Young Player of the Year), which he retained in 2005.
By the end of his debut season he was clutching Danish Cup and Superliga medals, and it was no surprise when, in June 2005, Agger won his first cap in a friendly against Finland. A few months later he excelled against Wayne Rooney and England before scoring his first international goal in a World Cup qualifier against Georgia.
A move abroad seemed inevitable, with the north-west of England his chosen destination in January 2006.
Denmark's most expensive export made his Reds debut against Birmingham on February 1, though injury meant his first few months on Merseyside were spent largely on the sidelines.
The 2006-07 campaign saw Agger force his way into the starting XI, and he even won PFA Player of the Month for September.
A 35-yard belter against West Ham did his kudos no harm, with the strike winning Liverpoolfc.tv's Goal of the Season.
The highlight of his first full campaign came in the Champions League semi-final second leg versus Chelsea, when his left-foot strike took the game to penalties. Agger went on to play 90 minutes in the final against AC Milan.
A metatarsal break left the popular defender on the sidelines for a large chunk of 2007-08 but there was some joy when Denmark's top players and managers voted him Player of the Year for the first time.
Over the next few seasons Agger would endure several more injuries that would disrupt his ability to help Liverpool's fortunes.
He did travel to his first major international tournament in 2010 - but sadly Denmark's World Cup was over at the group stage.
Back in domestic football, the Dane collected a medal with Liverpool in 2011-12. Much to the delight of the Kop, the campaign saw him become an almost permanent fixture on the teamsheet as he formed a strong partnership with Martin Skrtel and helped the club lift the Carling Cup.
With Brendan Rodgers installed as manager, Agger then committed his long-term future to Anfield by signing a new deal in October 2012. Four months later, the defender reached 200 appearances for the Reds when he featured against Zenit St Petersburg in the Europa League.
