Agreed, he seems lost. I think he also is simply not up to the job. He is too arrogant, refused to take advice from likes of Rangnick, wanted control over transfers and he has bought lots of his ex players or players that played well against Ajax. Its an unbelievably limited approach to recruitment and the club should never have sanctioned this, but equally he should have had the sense to realise how dumb an approach that was. Now most of these transfers have failed he is floundering. There is no tactical genius at work here, I think that was pretty obvious when he insisted playing Weghorst, the most technically limited player ever to play for us.
