Liverpool boss Rodgers convinced Suarez deserved penalty
Leon Barnett barged into the back of Suarez in the box and also brought his elbow down on the player's shoulder.
Referee Mike Jones did not award the penalty, much to the disappointment of Rodgers.
"It was a stonewall penalty," he said. "I feel for the guy (Suarez), I really do. Everyone in the ground knew it was a penalty.
"Antonio Valencia last week got a penalty against us and there was barely any contact.
"Today the young guy Barnett elbowed (Suarez) in the head and gave him a wee nudge just to make sure, but (Jones) still didn't give it.
"If Luis is a player who goes down too easily he would have done so in the second half when a defender caught him just before the fourth goal.
"Maybe one day we will get the decision. Until that point we just continue to concentrate on our performance."
