The Portuguese star has been in hot form in front of goal and continues to raise the bar for consistency
Ronaldo opened the scoring after 43 minutes at the Allianz Stadium before hooking in his second in the 58th minute after Parma had equalised just moments earlier.
Those efforts mean Ronaldo has now scored in seven straight Serie A games – the first Juventus player to do so since David Trezeguet in December 2005.
That run of form has also seen his overall league goal tally for the season increase to 16, handing him a record all of his own. Ronaldo is now the only player in the top five European leagues to score at least 15 goals in each of the last 14 campaigns.
Ronaldo has also become the fifth Juventus player to score 16 goals in his first 20 Serie A games, and the first since Omar Sivori in 1960.
Ronaldo struck 21 times in Serie A last season, with his current haul of 16 now the second best in the league behind current Golden Boot leader Ciro Immobile, who has scored an impressive 23 goals for Lazio.
With their star attacker on fire in front of goal, Juventus have now opened up a four-point lead at the league summit after second-placed Inter were held to a 1-1 draw against Lecce on Sunday.
Paulo Dybala claimed the assist for Ronaldo’s second strike against Parma, with manager Maurizio Sarri declaring prior to the match that it’s a myth the duo can’t play well together .
“It seems to me that Dybala is doing the best things this year with everyone, he is always doing well,” Sarri said.
“With him and Ronaldo, we have fewer players in the middle, but lately with them both we have always created and scored.
“I consider it a myth that the two of them have difficulty playing together, Cristiano is also scoring and I don’t see any problems whatsoever. They also scored with Gonzalo [Higuain], so I don’t see any problems.”
While Ronaldo has stolen the show in front of goal this season, Dybala has provided solid back-up, netting 11 times in all competitions.
