Tony, I see you still haven't realized that I am just messing with you about Iaquinta
I agree, he is a good, even excellent choice for a 3rd striker but will Juve use him as such ... if Trez stays or Gila or Huntelaar join, yes, but I am getting the feeling that Iaquinta maybe prepped to be a 2nd choice should Miccoli or Bianchi go to Juve.
As for Suazo having only pace, I can't agree here - he is very good with headers and has an excellent shot, both in terms of power and precision, and I for sure would prefer him over Iqauinta for the role of a 3rd forward namely because of his explosiveness and unpredictability.
Maybe you should check out some youtube clips - while they don't tell you anything about how a player would fit into a new team, they give you a pretty good idea what he capable of skillwise.
