Like I said, if you want player to create chances in final 3rd Willian is probably not your guy. I think most people want their winger to be fantastic in final 3rd that is fair. Then you need to have a team and system that suit that player. In the end of the day, that is what it is all about what kind of role do you want him to play.
In our case yesterday, Willian playing his role was needed. His running opened up everything for our offense, I can see pedro, Puli or Cho struggling in yesterday game.
