You are spot on with all of your points including those on Tuchel. I love him as a coach. My concerns are not his tactics.
But Hansi and now Nagelsman.
Julian was supposed to be the long term play. If he loses to PSG, go for it. But he didn’t. No doubt that “Neverkusen” is a bad loss as where others and other ties after the World Cup. To me, the timing is wrong.
I don’t think Tuchel was going to take a job (besides Bayern until the summer). Plus, if Nagelsmann lost vs Dortmund and Man City, you could then make a move.
I just think it was premature in terms of letting certain things play out. What if Tuchel fails? (he’s been put in a pressure cooker right off the bat) so it’s likely he fails through no fault of his own.
If he succeeds, sure, it looks great and all but definitely all eggs are now in the Tuchel basket and IMO, other jobs (Khan, board, etc) are on the line.
