Rodgers backed the Italy striker to shrug off 'unfair' criticism and end his six-game Premier League drought however, despite Balotelli missing another glorious chance in Sunday's 3-2 win at QPR.
The Liverpool boss said Balotelli's early Reds career has been blighted by comparisons with Uruguay forward Suarez, who completed a summer transfer to Barcelona.
The former Swansea manager bristled at suggestions Balotelli could have missed another sitter if Steven Caulker had not scored the decisive own goal.
"Wow, that's being very unfair: an open goal, from six yards?" said Rodgers when quizzed if Balotelli would have converted the tap-in from Raheem Sterling's cross.
"Well okay, that's harsh. It'll drop for the boy.
"The most important thing for me is his work, the guy's doing his best; he's working really hard.
"It's just not dropping for him at the moment, but I would have said he would have finished that, if young Steven Caulker had not turned it in.
"The criticism of him has been unfair, yes.
"And that's because he's probably seen as the direct replacement for Luis, and as I said before, Luis was irreplaceable and a real world-class talent.
"And that's not what's being asked of Mario. He's not going to be what Luis was.
"Mario's come into here, everyone knows him and they've seen him over his career, he's a great boy, and I've really enjoyed working with him.
"He wants to improve and be better, but it's not going to happen overnight."
