It's not only about Yildiz. The burden is on everyone.
Dusan has to show that if provided with better service, he is a striker clinical enought to convert those chances amap instead of missing again and again like he did this year. Chiesa is under more pressure. If Motta puts him back to his natrual position, he has to prove that he's still the same player before the injury. Maybe less explovise, but creative, unpredictable and lethal as usaul around the box. There's no more excuses of jihadball now.
Yildiz is not as stressed or eager to prove himself as Dusan or Chiesa is imo. He's not numero uno in the team. His talent and potential are clear to everyone but he is still raw. He needs time and any decent coach would give him time because he's simply the 3rd best option (maybe tied with Soule if we keep both) on the frontline. Since Motta plays a three men offense, I assume he'll have more consistent playing time and all he has to do is learn by experience, make real progress. Goals and assists will come.
