The Dane returned to the Reds' starting XI for their 4-0 victory over Fulham at Anfield after returning from injury to find himself out of favour for over a month.
His regular omission throughout October led to speculation over the 28-year-old's future, but Agger has insisted that he is happy to stay on Merseyside as long as he can contribute to the team.
"It is difficult to describe but I want to play all the time, every single game," he told reporters. "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."
Agger was one of several centre-backs to be linked with a move to Spanish giants Barcelona this summer.
