Struber would make a lot of sense. Austrian, red bull connection. Having said that I would be surprised if he didnt want a manager crack again. Poyet wouldnt surprise me at all. He strikes me as someone who would enjoy the overarching role, who would like having a vision to aspire to. He would tick my box of wanting some valuable experience as well, and he could well be the sort of voice KLD wants around him.Ferdinand spoke brilliantly on the overlap and will do a good job somewhere. Unfortunately, I'm always against anyone with links to them being appointed here because I think the fan base don't give them as much patience as someone without that link will get. The first bad signing we make, it'll be used as an insult to beat him with by some.
The Poyet and Struber links could have some merit. Neither of them have done that role before though. I'm not against it, maybe an experienced manager in that role is exactly the kind of support a young coach like Maric needs, but it's a transition for them and we can't have them overstepping their boundaries.
Edit to add I think Maric loves possession based football. That seems to be a directiom of travel for us. Poyet values possession too. Could well be a really good fit for everyone.
