Torres, Guirassy & Kane are the safest bets considering our finances.
Torres is a safety net, he is decent starting striker but below Barca ambitions (and history).
Guirassy is the cheap option.
Kane is the grandpa strategy.
Possibly a young signing with Torres, like the "Bro" kid from Molde, or Meite from Rennes, the later will cost 50M+ even for now, though.
PS: why isn't this in the Poll or General boards?
