Another vital member of one of Real Madrid's greatest ever squads, Karim Benzema has been Zidane's preferred striker for a while now. The Frenchman signed a new contract last year, which put his release clause at this staggering amount.

Signed from Lyon in 2009, the 30-year-old has spent most of his senior career at Real Madrid, raking up 126 goals in 263 appearances for the club.
Benzema has all the characteristics of a top striker- good physicality, good finishing and his hold up play is excellent and allows other forwards to flourish. Despite his poor run of form lately, he would go straight into the starting XI of several top teams. He still has a few years left to perform at the top level and will be looking to make the most of it.
