"You are not going to win a title if you are drawing every second game - we know that," said Agger.
"But games like this one against Portsmouth, where we have won after going behind, are a big bonus for all of us. We worked hard for the win.
"The way the game turned out was not the way we had planned for it to be, but the most important thing was to take the three points, so we are just relieved that we did that.
"Every game is only worth three points, you don't get any extra points for coming back but it always gives you a massive boost if you can come from behind."
