So you think that period was irrelevant?
Canb you find anything he posted which might lead to thaht conclusion?
You don't think the players went into their shells for 17minutes, and Tuchel reacted by making his first sub?
Again, where has he said anything approaching that?
You are reading him not saying things as meaning the opposite of what you mighth have said, when it actually just means he hasn't commented on that matter.
If he'd done nothing you can be certain he would still be blamed for ARG goals, which I think we agree were inevitable with the defensive mindset the team took up, against that ARG attack.
I don't think there is any argument there. The question isn't whether he should have done nothing, but is rather about whether going more defensive was really the right choice, or whether he might have been better swapping fresh legs for tired ones, but keeping the same shape.
With 20:20 hindsight, going more defensive doesn't appear to have been the right choice.
