Again, I never said I'd prefer him over Dzeko. I didn't really read many posts here so no idea if anyone said that.
Price is a complicated thing and many factors change it. Like only the fact that he's a talented Brazilian will raise his price, Brazilian market does that same as it's one of the most expensive markets out there. I agree price sounds high but you take the risk and pay the potential he offers.
Kaka, world class player, choked in Madrid so we can't be sure Dzeko would shine and Neymar would flop, it's why I said every business activity involves taking risk. Benzema also had huge price back in the days and now we have Lukaku who also costs a loooot and why? Because he scored 100 goals for youth Anderlecht? Well, yes and no. It's potential we go after usually and this guy surely has it.
