I'm glad my list is taking so much
intention
I chose that ranking based on ability and pricetag. Falcao was bought recently by Atletico Madrid for 40 mil or so and he's an indispensible member of the team, they will try to get more cash for him. Dzeko isn't that important to City and could be sold for much less.
Ability-wise, yes, Falcao could be the better player.
