I agree. Many say he hasn't proven himself or earned this trust, but that is not relevant. These players have over and over proved themselves, as useless, and should never be backed over a manager again. If you turn on ETH now you give the players, Murtagh, Fletcher, Arnold, and ultimately, the vermin Glazers, yet another patsy to buy more time instead of addressing the real issues.
What he does need to do is adapt. He should have been making subs after less than half an hour yesterday. It will be abundantly clear to him right now that these players are wasters and not able to execute his vision. If he doesn't show pragmatism from here until he has what he needs, then he will never reach the point where he has what he needs. If he sets the team up against Liverpool to play out from the back like yesterday, the result could be worse than last seasons farce. As long as he shows some level of pragmatism, then I think all anger should be aimed at those above him. However, if he keeps trying to play his Dutch vision with DDG, Maguire and McFred then he will rightly get what he deserves.
