A system that doesn't leave the defense exposed with acres of space behind, in which every opponent attack is already half a chance
Xavi's system didn't have these flaws. We often sat back, especially after leading. Araujo looked like top3 defender in the world thanks to this.
a system that doesn't play the offside trap in the halfway line like amateurs who dont know the rules of the game.
We didn't do that under Xavi.
A system that doesn't rely on "intensity" 90 minutes of a game, as if the players are robots.
We didn't do that under Xavi either. We had in each game parts to sit back and let the opponent play.
A football game requires adaptability during certain points of a match, not asking to park the bus, that's black and white thinking.
That's exactly what Xavi did. He always adapted to play either more offensively, or defensively according to the opponent. You can check the statistics for example of LL and CL/EL games and compare them.
So Yes, we did.
But even so, no, i wasn't confident with Xavi
So what now, you didn't feel confident in the things you demand yourself here? Or is it maybe a bigger and much more complex picture than just criticizing a system? Maybe a few other things play a part as well to feel confident, like having hundreds of millions to spend or not, having injuries or not, having luck or not, having a deep squad or not and many others.
Your stratement "not feeling confident" with flick ignores absolutely everything, above all a domestic treble and one minute away from a CL final, while contradicting your own demands by giving you your system we failed miserably with Xavi.
If you say something like this, then provide a realistic solution and combination you feel confident with. Otherwise it's just empty words.
