I guess that if Kolo Muani turns his 7th-minute opportunity into a goal, things will be different. Then, would Juventus have a world-class striker or not? Just because a striker can lose a chance doesn't make him useless or amateur. Plus, they already signed David from Lille, but they will probably lose Vlahovic.

Losing Vlahovic is gonna be their best decision, but also bad if they can't recoup some money from him. He has been so bad. If you're watching his team's game against City. You may be familiar with that moment.
It was the moment when Vlahovic missed easy peasy chance. It might be a goal if he just pass it to the Koop.
No doubt many feel so desperate with him, and wanted him to leave.
