There have been a lot of assertions in this thread about the scoring performances of Dzeko, Aguero, Tevez and Cavani. Here are some CAREER statistics in the major European Leagues taking into account time actually on the field. Ranking them in terms of minutes per goal:
Dzeko [Bundesliga + Premier League; 2007 +] 96 goals @ 137 minutes per goal
Cavani [Serie A; 2006 +] 112 goals @ 149 mpg
Aguero [Primera Division + Premier League; 2006] 109 goals @ 162 mpg
Tevez [Premier League; 2006 +] 84 goals @ 174 mpg
If penalties are excluded, the mpgs are D 140: A 172; C 178; T 205. (15% of T's goals have been penalties; 16% of C's goals have been penalties).
There has also been much asserted on here about what various strikers also offer. Here are their MINUTES PER ASSIST for those same games:
Dzeko 321 mins per assist
Tevez 340 mins per assist
Aguero 422 mins per assist
Cavani 618 mins per assist
Oh, Look! Dzeko is better than Tevez! And Cavani is way behind the others.
