The poll is a tricky one... I voted against giving him another year. But to be perfectly honest, I actually wouldn't get rid of him as long as I don't know who will take over from him. The club acted dumb enough in the past to bring in a Simeone, a Conte or Southgate. Heck I wouldn't even put it past them to bring in Rafa. I'd take ETH for another season if the alternative isn't good.
I think, the criticism he gets tonight is a little weird in terms of point in time. I mean, obviously I get the frustration but I think, for the first like 70 minutes or so, we played one of the better games in the last 3 or 4 month. It was a professional performance, we just succumbed to the pressure at some point and then a combination of breakdown due to weak mentality and some luck on Coventry side (with their 2nd and 3rd goal).
Today didn't really bring anything new to the table - our defensive plan is problematic, the injuries make that even more striking. A midfield consisting of Bruno, Eriksen, McTominay for large parts of the game was bound to be problematic because none of them has the skillset of an above average CM.
I lost hope that ETH is capable of turning this around. I think, his challenge was pretty big taking into account off field issues like Sancho, CR7 and Greenwood, which all (probably bar CR7) should have been corner stones for a United attack that at least has more chances for individual brilliance which in the absence of a good plan would at least have upped our chances of scoring every once in a while. The injuries also don't really help. But all in all I think he put his hope onto the wrong players and will now have to pay the price for it.
