I don't see Falcao or Cavani happening.
Barcelona really need a striker, unless they want to wear out Messi.
Bayern could buy Falcao or Cavani as a present for Pep.
Citeh and Real also have money to blow.
Juventus is still to use its striker budget.
That's 5 big teams that have a need (real or imagined) for a big name striker.
If I'm Arsenal, I let them have Falcao or Cavani, but then I go in and grab whoever is affected by such a purchase. The likes of Mario Mandzukic, Edin Dzeko, or Gonzalo Higuain or even a David Villa could find themselves homeless.
