The Reds were trailing 1-0 until the Northern Irishman altered his formation from a 5-3-2 set-up to their favoured 4-2-3-1 layout.
Nuri Sahin made way for Spanish starlet Suso, with Glen Johnson dropping to left-back, allowing Jose Enrique to get forward.
This saw the travelling side take control of the game and eventually equalise through Luis Suarez.
After the match Rodgers explained his decision and praised his players:
“I thought in the first half we were too tentative. Second half our attitude in the game was much better and we are better when we play fast football.” He told SkySports.
“Coming here is a very difficult place. I thought it was a great point for us.
“You have to give credit to the players, they were fantastic.
“Whatever system you have, it doesn’t matter, it is about the application and the quality of the players.”
Veteran defender Jamie Carragher had a telling contribution in Liverpool’s goal, with his glancing header being met by Suarez for the simplest of finishes.
Although he is far from being a first-team regular, Rodgers praised his defender’s attitude and ability:
“He is phenomenal, it’s an absolute pleasure to work with him. His preparation is first class, he is always preparing himself well.
“Today he was exceptional, he is a real model professional for a young player. With everything he has won and achieved he could easily come and knock on my door but he is old school, he respects authority.”
John Terry put Chelsea ahead with a trademark header in the first-half, before Suarez nodded home following a corner-kick.
