#2 Karim Benzema

The fact that Karim Benzema hasn't been offloaded so far and continues to manage a starting spot at Real Madrid is inexplicable, but it is what it is. The Frenchman has found himself in the firing line for the better part of this year, as he hasn't measured up to the standards required of a top-quality player at a top-level club.
Needless to say, Real Madrid have been disastrous in LaLiga this season, and much of it can be attributed to their offensive woes. Benzema, who spearheads Real Madrid's attacking unit, has only scored 5 goals in 15 appearances in LaLiga this season. It goes without saying that a lot more is expected of a player holding such a position.
If Benzema's form continues as such, which looks to be the case at present, his days at the Santiago Bernabeu are definitely numbered, and Real Madrid won't have to think long and hard before cashing in on him.
