The Uruguay international has netted 10 of the Reds' 17 Premier League goals so far this term but Johnson does not feel there is too much of a burden on his shoulders.
"We are not relying on Suarez at all," said Johnson. "Obviously he is our main striker, but we are not relying on him.
"It's everyone's job to get around him and try and score.
"You need a bit of luck in front of goal and on another day we might have had two or three (against Swansea City on the weekend)."
