Inspired by the discussion regarding Dusan at the last post. His stats regarding goal distributions are worth looking at. He struggles vs all non relegation sides.

So in 2.5 years at Juve he has only scored 10 goals vs top 12 table clubs of Serie A. That's in a 60 games worth possible. And if you narrow it down to top 4 sides (20 games), he has scored only once vs Inter last year.
Goals vs smaller teams are important too, but these are not the numbers you would expected from one of highest paid players in europe.

He's also non existent in the build up, and not a physical striker like past Lukaku/Giroud either. I don't think he's the guy to build a project around. Would like to be proven wrong by him this year tho.

He also has gotten a new coach and more quality teammates, I don't think he can have more excuses.
