Being indirectly involved in the goals or even have contributions in the build-up play is something which you don't see in the stats.
Then again, why would you bring Dzeko in this context?
The point was, which one is worse, Arnautovic or Correa. And now you're bringing useless points into discussion, like replacing him or whatever, which I never said he has to stay or if he's good enough for Inter. Point was that he's done better than Correa, why would you bring up useless points into discussion?
