With Martin Skrtel, Kolo Toure and new signings Mamadou Sakho and Tiago Ilori also in the picture, Agger faces competition for places, and his early season injury pushed him down the pecking order, with £17m man Sakho getting the nod.
Now having recovered fully, Agger is back in the picture and returned to the heart of the defence in Liverpool's 4-0 win over Fulham at weekend, but the period out of the team was clearly tough to take for the Danish international.
“It is difficult to describe but I want to play all the time, every single game,' he said. When you are not playing that is difficult but, while that is sad, I just try to work even harder every single day in training, not complaining just doing everything a bit extra.
“I am more than capable of being in the team - I feel I belong there - but it is the manager's decision and sometimes that is difficult to change in training. You need to grab the chance when it is there - that is what football is all about. I know I am here and as long as I am doing everything I can to be in that team, and I feel I am good enough and the manager can use me, then I'll be here.
"Competition is what this club has been about and should always be and that is a good thing because we want to win something,' he said. I'm not the type of player who needs an explanation, I just carry on with my thing and try to do everything to get back into the team. It's been a bit longer than I hoped for but when you get the chance you need to do everything to keep your place.
Whilst speculation over the summer linking Agger with a move to Barcelona, it appears the former Brondby man is prepared to stay at Anfield, and his path to the first team may be clearer if Napoli boss Rafa Benitez firms up his interest in his former defender Martin Skrtel.
Should Agger be a first team regular? Should the Dane have to fight for his place? Comment below.
