It really is a strange one. Rangnick has long been mooted as wanting to work in the background and building clubs up, and you'd have to say has been exposed as a poor manager no matter how toxic our squad is currently, so what is there to achieve at Austria?
He can't impact the players at his disposal and build them up as if they were a club side, he'll get hardly any time on the training pitch to implement his favoured pressing style of play, plus you've got the fact the last 6 months of him analysing the squad in order to perform better in a consultancy role have just been wasted.
Be really interesting to hear his thoughts on the matter in the coming months.
