Wigan manager Roberto Martinez accused Luis Suarez of a stamp after the Liverpool striker's match-winning performance at Anfield.
The Wigan manager claimed the Uruguayan stamped on Latics midfielder David Jones in the 63rd minute of the match, which Liverpool won 3-0.
"He was very fortunate because there was a stamp on David Jones that the referee didn't see," Martinez said.
"That wasn't the sign of a top player. He was fortunate. He was lucky."
Suarez scored twice in the second half and helped create a third to give Liverpool only their second home win of the season - but Martinez's comments may put the controversial striker in the spotlight again.
"I have not mentioned it to the referee," Martinez added. "The things that may happen on a football pitch should be judged by the referee. Those are the incidents that happen. It wasn't a nasty game, a bad game.
"But when you see the replay it is a clear stamp. It could have been a red card if the referee had seen it. But I am not one to look back."
Everton manager David Moyes also claimed Suarez was fortunate to escape a red card for a challenge on Sylvain Distin in last month's Merseyside derby.
And he has also been accused of diving to win penalties for his team, with Stoke boss Tony Pulis calling for the striker to be banned for trying to con referees.
With his ninth and 10th league goals of the season, Suarez has moved above Manchester United's Robin van Persie to top the Premier League scoring charts.
But Liverpool boss Rodgers - who had already spoken to the media before Martinez made his accusations - was keen to insist that despite Suarez having scored 10 of his side's 17 league goals this season Liverpool are not over reliant on their striker.
"He is a master marksman, absolutely outstanding and we are thrilled to have him. But the ethos is very much about the team and the team were excellent today," Rodgers said.
"I thought the team was outstanding today. Luis took his goals very well, his movement was outstanding but today was a result for everyone and I was delighted with that performance.
"It is not just Luis Suarez. Luis Suarez finishes off the great work."
