With all the respect in the world, that's nonsense.
By all means, if you really, really have to, then go 4-5-1 and sit deep and try to play out a 0-0, but foregoing strikers altogether and playing a 4-6-0 is a complete middle finger up to the entire sport. I'm not a massive Scotland fan, and certainly I wouldn't travel abroad to watch them play, but had I been at the game tonight, I would've been absolutely furious.
Accepting that you'd be outclassed in an all-out attacking game is fine, but completely abandoning all hope of attacking before a ball is even kicked is shameful, especially against a fairly average team such as the Czech Republic.
Any team that plays without strikers should be roundly shunned by everyone, no matter who it is or who they're playing.
