Despite taking the lead in the Champions League crunch match, the Reds surrendered it in the dying seconds of the game to leave their hopes of qualification to the second round of the competition hanging by a thread.
But there was real signs of grit and determination throughout the game and Agger believes the golden sky at the end of the storm is just around the corner.
“You get what you deserve in football and you have to look at closing the game down otherwise you get punished in the way we did in Lyon,” said Agger.
“Now we have just got to look forward to the Birmingham game to get going. If we keep playing with the effort we did in Lyon, we hope the situation will turn for us.
“It’s always so difficult to accept when you lose two points in the manner we did so late in a game.
“We were all so disappointed. We might have controlled the game but it’s no consolation; you’ve got to keep working hard until the last minute.
“But we have to keep believing. We have got to go into the next two games, make sure that we win them and then take it from there.
The Reds next take on Birmingham City in the Premier League at Anfield on Monday night. Tickets are still available by contacting the club’s ticket office.
