Having missed a host of presentable chances against Iceland before lashing out at their "small mentality", the 31-year-old, who comes into this tournament off the back of a sixth consecutive season where he scored 50 or more goals for Real Madrid, drew another blank against Austria on matchday two.
Not only did Ronaldo fail to score but the exclamation point on his barren run was a late missed penalty at the Parc des Princes which left Portugal third in the group going into the final round of matches.
The two-time Ballon d'Or winner became his nation's most capped player against Austria, but a fourth missed penalty in his last five attempts for club and country ended the night on another sour note.
Another unwanted record is Ronaldo's run of 36 free-kick attempts without finding the net at major international tournaments. bet365 go 8/1 (9.0) that Ronaldo breaks that streak by scoring a free-kick against Hungary on Wednesday.
Ronaldo's Real Madrid team-mate, Gareth Bale, has had no such issues with his set pieces, notching against both Slovakia and England so far, but bet365 go 10/1 (11.0) that the Wales frontman completes a remarkable hat-trick in their crunch Group B clash with Russia.
The same firm go 11/8 (2.38) that Bale finds the net at anytime and it's just 4/6 (1.67) that Ronaldo scores his first goal of the tournament in Lyon. Those expecting a dominant performance can back 11/4 (3.75) on the Portugal forward scoring two or more and 10/1 (11.0) on a hat-trick.
