The Portuguese star has scored just once from his 55 attempts on goal in La Liga matches, meaning his shot conversion rate is a mere 1.82%.
That is the lowest percentage of any forward with one goal or more in La Liga, the Premier League, Serie A, Ligue 1 and the Bundesliga.
Benzema, another 'Los Blancos' star who is yet to find his shooting boots this campaign, comes in as the 20th worst forward with a conversion rate of 5.56% (one goal from 18 shots).
Another big name on the list is Arsenal's Alexis Sanchez. He has managed just two goals from 32 attempts on goal, giving him a shot conversion rate of 6.25%.
Real Madrid will be hoping for an improved performance from their attacking duo when they face Apoel Nicosia on Tuesday evening.
