Speaking to Betfair, Dimitar Berbatov said: "When teams have a bad result the star players always end up with the blame.
"And at the minute with Manchester United, that's Cristiano Ronaldo.
"At the moment he's got just one goal in ten games and that seems problematic for everybody, but not for me.
"There are eleven players on the pitch and the blame should be shared. Ronaldo is an icon in the world of football and people need to remember that he's 37.
"So, from time to time he is allowed to have a couple of bad games. But I don't think that is the problem here."
Ronaldo cut a frustrated figure against Atletico Madrid and Watford last week with Man United having to settle for a draw in both games.
The 37-year-old forward has only scored one goal so far in 2022, the winner against Brighton at Old Trafford on February 15.
