Rodgers was speaking after the Reds reverted to a 4-3-3 formation for Saturday's 4-0 win over Fulham, with Kolo Toure rested and Daniel Agger joining Martin Srktel at the heart of the defence.
Rodgers says more players will taste first-team action over the busy festive period as the second-placed Reds look to push on from their strong start to the Premier League campaign.
He told the club's official website: "I just decided to change it (on Saturday).
"I have said to the players that between now and January we have one game a week.
"The players are working very well and very hard on a daily basis but I need to give oxygen to some players, so they can see a light at the end of the tunnel.
"It is important that I use the players well.
"Kolo has been sensational since he has been in but Daniel Agger is a top player. I just need to balance the team out when I can."
