7. Karim Benzema | Real Madrid
Real Madrid are the biggest club in world football - and, subsequently, their main striker should be scoring at least 20 league goals every season.
However, Karim Benzema has only scored more than 20 La Liga goals in one of the five campaigns - including the current one - in which he has played at the Bernabeu.
The Frenchman’s profligacy, though, has been largely overshadowed by Cristiano Ronaldo’s brilliance.
