but I don't think it's completely unfair in this instance.

He's trying to blame the team now for being too passive - his whole attitude after the goal was that he didn't believe his side were capable of getting this done other than by getting their backs to the wall, and that was picked up loud and clear by Argentina.

All those defenders and they still allowed Messi to do that.

It's not down to any one single decision or individual, but Tuchel hasn't done well tonight. For the tournament, I'd say about par - semi final is about their level but they didn't get there in style and can't complain realistically about not getting further.
