I don't think Slot is scapegoating Gravenberch; he's trying to ensure Trent isn't being totally singled out, which is understandable.
A defensive midfielder does bear some responsibility if one side is consistently overloaded with players and chances. While these situations are always a collective issue, it doesn't take away from how utterly woeful Trent was. If Slot had called out Trents lack of effort and tracking back then he couldn't have complained, but it would have put further spotlight onto why Slot left him on the field as long as he did. Why he did is anyone's guess, but there could be reasons we don't know about. From the outside at least it was a glaring error.
