The Dane suffered a tear to his abdominal muscle in September but, after his return from the injury against Fulham, hopes to have impressed Brendan Rodgers enough to keep his place in the side.
Reports had suggested that the emergence of Kolo Toure and Mamadou Sakho combined with the rejuvenation of Martin Skrtel would see the Reds' vice-captain forced out of the door but Agger is undeterred by competition for his place.
The defender told The Guardian that talk of an exit is "nothing to do with me".

"It's been difficult," the Denmark international admitted. "It's hard to describe and I want to play every time in every single game so, when you're not playing, it's difficult.
"But, when that is said, I just have to work even harder every single day in training, not complain and just do everything that little bit extra.
"I feel I belong there. I feel I'm more than capable of being in the team but it's the manager's decision. Sometimes that's difficult to change in training. You need to grab the chance when it's there and that's what football is about, taking your chances.
"There has always been competition for places at this club and it should always be intense. That's a good thing because we want to win something."
