As a team, a struggling Real Madrid have scored 32 times in 18 league games this season, making them less prolific in front of goal than Real Betis, Celta Vigo, Real Socieded (all 33) and Valencia (40), while fierce rivals Barcelona have hit the net on 20 more occasions.
Ronaldo himself, while top scorer in the Champions League with nine goals in six games, has managed a paltry tally of just four goals in his 14 appearances.
At his current rate of scoring, the 32-year-old might just reach double figures. To compare, his least prolific La Liga season at Real to date (2016/17) saw him net 25 times in 29 appearances.
The last time he failed to score double figures in a league campaign was more than 10 years ago in 2005/06 when a 21-year-old Ronaldo netted nine Premier League goals for Manchester United.
Taking to Instagram, Katia sought to remind Ronaldo with a lengthy post of all the previous occasions that people have tried to bring him down, only for him to consistently defy his critics time and time again.
"When you came to Lisbon at the age of twelve, full of tears and hopes, they said that you were just another Madeiran kid. In less than five years you were playing in the main team of Sporting," she wrote on the social platform.
"When you played the first games with the seniors, they said you were just another skilful f*ck. A few months later you signed for Manchester United.
"When you arrived in England they said you were only a prospect. In six seasons you scored 118 goals.
"When Real Madrid signed you, they said you were just a name to sell jerseys. Since 2009 you have scored 422 goals in 418 games and you've practically beat all the records you had to beat the club.
"When you received the first Ballon d'Or in 2008, they said it was going to be just that. You've earned four more.
"When you became captain of the national team, they said that you were just another captain with no charisma, no spirit of leadership. In 2016 you were the first Portuguese ever to raise the European Championship trophy.
"Now that you do not score as an extraterrestrial there are two or three games, they say you are just another late-career player, almost finished, to take the last, down the curve.
"Do not worry. When you smile with a trophy in hand at the top of an Eiffel Tower of this life, or when you score another decisive goal, or when you break another record, you will have them there watching you, attentive. To applaud, of course. Poor people. That's all they have left."
