Ouch
One thing I will give Tite is I liked the starting lineup he ended up running with, even if the way he had them attacking and pressing was stale.
Playing another creative midfielder with Neymar and Casemiro was the right decision IMO and I hope your next coach doesn't opt for a more pragmatic lineup...even though with Fabinho & BG, you certainly have quality options to play the double-6 next to Casemiro.
I'm firmly in 'the lean into your strengths' camp at the international level. At the club level, cohesion and versatility can consistently win for you, but at the international level you need to work with what you've got more.
