Sunday's goals project to be the first two of many scores for Ronaldo in a Juventus uniform.
Ronaldo is the joint-highest rated player on the game with Lionel Messi on 94 but Moberg joked about the fact that Ronaldo's physicality rating is lower than his.
"The important thing is for the team to win, and maybe I was a bit anxious, as is normal, after leaving Madrid and everything that happened".
Ronaldo scored 44 goals for Real Madrid last season including 15 in the Champions League on the way to a third straight title.
His first, in the 50th minute, was probably the worst goal he's ever scored, before he followed it up with an emphatic left-footed finish to take him to 400 league goals in his career.
"So there were a lot of expectations, but I thank my teammates for supporting me throughout".
Allegri congratulated Ronaldo for breaking his duck before their trip to Spain to play Valencia in the Champions League next Wednesday.
Ronaldo could have completed a hat-trick late on but missed two easy chances from inside the penalty area. The victory was tarnished, however, by a lamentable spitting incident involving Douglas Costa.
The Brazilian winger was seen intentionally spitting in the direction of Federico Di Francesco's face.
Juventus, which is seeking a record-extending eighth successive Serie A title, is the only team still with a ideal record. He is up and running and his three-and-a-half game drought (!) is over.
Gonzalo Higuain also got off the mark for his new club but AC Milan was held to a 1-1 draw at Cagliari.
And now Costa has released a message apologised to Juventus' fans and his team-mates, insisting it will be an isolated offence.
