Right now Ange is out of his depth, has he got the smarts to correct it at this level? I am not so sure! I really do hope so but I am afraid he's too stubborn and won't adapt, we've been shocking at set pieces since the Emirates Marketing Project cup game and he refuses to accept it is important enough to address no matter how many games it's made the difference in.
When managers make obvious errors it usually means he's a busted flush and it's only a matter of time. For example bringing on Gil who hasn't played for months and has definitely been deemed not good enough/ surplus to try and change the game sets off alarm bells for me, it says to me he is totally out of ideas.
He is blaming the players for not believing in his system and then shouting at players from the sidelines, if he hasn't got that message across by this point in the season it's no good digging players out in front of the world during the game, that's on him. After he did that everybody was afraid to pass backwards and there were some very poor decisions made.
He adapted well to loosing players earlier in the season so he can obviously think on his feet but he's not been prepared to adjust tactically to teams working us out, the demise of poch was that he struggled to adapt his tactics outside of his "philosophy" other than "Llorente longball" (along with replacing dembele with sissoko). I hope Big Ange doesn't suffer the same rigidity and comes back swinging.
