Well said.
Ange is and was well within his rights to experiment. I personally feel he went a bit too far (as I said, I wouldn't have changed the FBs as he's seen plenty of Davies in pre-season and Royal played against Brentford), but it's clear that he isn't yet settled on which players he can trust moving forward, and which need to be moved on.
Some it seems he does have clarity, like Ndombele and Dier.
Others? Far less obvious. GLC is a good example of this. Ange was full of positive comments about him over the summer and how he wanted to utilise him, but then when push came to shove he sees he had a terrible game. That may have given him the clarity he was previously lacking. Hojbjerg similar. Here is a player who could leave before the end of the window, but does the manager want to lose him? Perhaps last night answered that question.
The timing of it was nasty and I personally don't think any cup competitions should start until after the window has closed (neither should the PL to be perfectly honest, but that envelope is definitely too big to push), simply because it opens the very real risk of players being cup-tied having featured in just one or two rounds! But the defeat will only be the disaster many are painting it as, if the lessons aren't learned and clarity isn't gained.
I'm as hungry for a trophy as any Spurs fan but right now this is a very long marathon, not a sprint. We have 4 years of insanity to unravel.
