I rate Falcao more than Hulk but I can't see a place for him at Barca since the central spot is perma-occupied by Leo. Hulk can play anywhere in the front three, even though he's best cutting in from the right, from what I've seen. As for the price though, I don't think they'll leave for cheap. It's Porto after all.
Agreed on Falcao. And yes Hulk is versatile up front, which makes him more valuable.
Best of all he has that physical presence, we are in such vital need of, AND at the same time has incredibly good technical ability.
Playing on the right so well is a very good thing too, b/c I have NOT been impressed with Pedro at all this season. Bojan, altho having good potential, is still too young to play in big games. Thus, he'll be a good competitor for Pedro, and Bojan, while being capable of replacing Villa or Messi if those two are injured.
Regarding price, most likely cheaper than Rossi, Nilmar, or that young brazilian kid. Can't really say the experience w/ Lisandro (24 mill euro) will be repeated, since that guy left when market was crazy w/ madrid inflating the market in 2009. And as far as I know, no club has showed great interest in Hulk --> no bidding wars and overpaying for us.
