Never mind just being Liverpool's best ball-playing defender; Agger is arguably Liverpool's most gifted defender all round.
Not only is he comfortable in possession, but his positioning, awareness and ability in the air appear to have improved over the last 18 months.
His performances led to talk of a move to Manchester City—as reported by Jack Wilson of the Daily Star—but this never materialised, and Agger has since pledged his future to the Reds for as long as they want him, per Danish paper Ekstrabladet (h/t the Express).
As well as being Liverpool's most gifted defender, Agger is arguably one of the top defenders in the Premier League.
Vincent Kompany apart, there is nobody that stands out as being as good or as reliable as Liverpool's Danish international.
The likes of John Terry and Rio Ferdinand have been top, top defenders throughout their careers, but in the current era, it is this writer's opinion that only Kompany eclipses Agger as the Premier League's best defender.
Like Kompany, Agger oozes authority and a "thou shall not pass" attitude to defending.
For Agger, it is "win at all costs." Very rarely has a player come from abroad and had such an affiliation with the Liverpool fans.
Comments of wanting to remain a Liverpool player for as long as he is wanted and YNWA (You'll Never Walk Alone) tattoos across his knuckles have endeared him to the Anfield faithful.
What Liverpool and the fans need now, though, is Agger back where he belongs, at the heart of the Reds defence, providing a calmness and sense of security for those around him.
At the moment, Liverpool have a good side, but with Agger in there they are a better side, a more solid side, and in the Dane they have a natural born leader desperate to steer the ship, should he ever be called upon.
The sooner he is back in the starting 11, the better.
Do you agree? Should Agger return to the Reds starting lineup, or have Toure, Skrtel and Sakho done enough to warrant their inclusion? Leave your opinions below.
