Possibly.
I don't want dinosaurs like Warnock - that's a huge 'NO', for me - but younger guys is fine, as long as they have an ability to implement a certain style. Salzburg can appoint youngster after youngster (Marco Rose, Jesse Marsch, Thomas Jaissle all come through their academy) because they are able to implement a certain style.
We should also be able to attract managers from smaller leagues, like Knutsen - unless his status is higher now after their European exploits. I know our finances are limited, but they're still higher than many clubs.
