Iraola was new to the league, figured things out and got better. As I've posted elsewhere, his losses were also to the big 6 plus Brighton. They held Chelsea to a draw and then had two disappointing losses which could have seen him go if it continues, except results turned. So it took him 10 games to find his feet in a new league.
Ange lit the league up, for 10 games. Then crashed, hard. That crash has never improved, never picked up, and actually he's slipped even lower. Consistently, over 66 premier league games he's failed to turn Spurs around from, let's face, the low point he put them in.
So what is it exactly that makes you think Ange can do better here? What makes you think he's the man for the job? That he can deliver wins and consistent results at a team with less resource, less stature, inferior squad, to the one he consistently failed at?
You can be condescending and clever talking about the cognoscenti and whatever else. It isn't a case of having no patience - it's that many of us believe a mistake has been made. If you make a mistake then the quicker you can rectify it the better. Just blithely continuing and trying to pretend the mistake was not a mistake, does not fix the mistake.
