马尔基西奥质疑伊尔迪兹被换下：我绝不会把他换下，他太重要（马尔基西奥不满伊尔迪兹被换下：我绝不会这么做，他至关重要）

Considering how to respond thoughtfully

I need to respond carefully and acknowledge the user’s questions. I should ask which game they're referring to or suggest possible questions. It’s important to provide a balanced perspective, discussing why a coach might substitute a player, as well as why Marchisio values them. I can also offer to find the original article if they provide a link or ask if I can use the network for that. But it’s safer to clarify if they want me to look something up and keep my answer concise.
