Dzeko: 45 games, 21 goals for Bosnia
Llorente: 20 games, 7 goals for Spain
How is he more efficient?
Llorente: 236 games, 79 goals for AB (from 2005 to present)
Dzeko: 111 games, 66 goals for Wolfsburg (in only 4 season with ze Germans)
When Dzeko gets consistent playing time, he outscores the Spaniard easily. And Dzeko is a year younger.
Dzeko for the win.
