Bite your tongue! That's not how you Blitz!!
Coaches don't need to learn what players they've never coached in proper games before can do, or what their shortcomings might be, . or how much fitness they have after 12 months off,.. or who works best where & when!!!
They should just be able to divine this through their magical ways & have it all perfect straight away, NOW!!.. And all the time, always!!
NO FKN EXCEPTIONS!
Now that's how you Blitz ...
