However, speaking ahead of the FA Cup sixth round tie against Sir Alex Ferguson's side on Saturday evening, the Fulham boss has said that he does not believe that is the case.
"To be fair, I don't think in the situations I've seen there's been a lot of blatant diving from Ronaldo," said Hodgson.
"At the speed he goes at, when he loses control of the ball and people are in there making attempted challenges, the referee has a difficult task on his hands.
"Take the penalty incident in the Carling Cup final (when Ronaldo was booked for an alleged dive in the penalty area after being brought down by Ledley King).
"I must have watched that 15 times and I'm still not 100% convinced either way.
"I don't think Ronaldo is definitely diving and I'm not convinced he was definitely fouled by Ledley King.
"Ronaldo is the greatest example in our league but there are other wingers who run with the ball at pace and when you are confronted with that you have to be aware that with a rash challenge on your part, with the speed of the player going past you, you could be giving away a penalty without attempting to do anything other than make a tackle.
"Manchester United switch the play very well, so if Paul Scholes has hit a 70-yard pass at the speed of light onto Ronaldo's boot and your full-back, Paul Konchesky in this case, is trying to get out there, it's a dangerous situation.
"Discipline, caution, staying on your feet, being prepared to run with someone, being prepared to accept he might go past you and that you'll need to make a second effort, they are the crucial factors for us tomorrow."
