Moberg tweeted the Portuguese forward with a photo that highlighted the fact that his own rating for physicality was 81, whereas Ronaldo's was two lower at 79.
Moberg plays in Norway's top flight for Bodo/Glimt.
The photo was tweeted before Ronaldo opened his account for the 'Old Lady' on Sunday, scoring twice against Sassuolo.
The 33-year-old said in May that he had a biological age of 23, and that he could keep playing until he was 41.
