Both Graham and Wenger had been unknown but not inexperienced.... that's why going for unproven guys like Rose/Wilder/Howe isn't that bad of an idea. My fear though is that our dumb board wants someone like Arteta simply because they just want a figurehead in charge of the team while the same coaching/recruitment guys who sank Emery get to keep their job. If that's the case then we will be in trouble.
I'd be far more comfortable with the category of Rose, Wilder, Howe, Stéphan, Marsch, Fonseca than with Arteta, Vieira or the category of Ancelotti, Marcelino, etc. Club should stick with Ljungberg and hope for the best until the end of the season, then try to tempt one of the first category and/or see what happens in the Bayern - Ten Hag - Tuchel triangle.
