Radamel Falcao vs. Kun Aguero who (and why) would you buy if you were Real Madrid manager?

Real Madrid don't need another forward, Benzema and Higuain are more than enough, what they need is a better manager who is brave enough to use them when it matters, Mourinho $hits himself when facing Barcelona and thats why he never uses them, Pellegrini was a great coach, they should have retained him.
