Some thoughts.
Finances. The financial situation of the club is in such a mess I don't expect it to be solved quickly or in the summer window. This factors in for a number of reasons, including what it would cost to sack the head coach and all his staff (placing greater strain on an incredibly tight ship) and also because despite telling him he could not come in the summer and it needed to be immediate, we have not been able to address even some of the smaller issues in one window (despite there being long standing issues on the quality of the squad or being able to sort it in the immediate term).
Injuries. Yes it's nothing like last season but those that are injured are of such vital importance (Martinez, Amad, Mainoo for example) or are able to just offer other options than what we have (Mount, Shaw, Collyer for example) I struggle to see what other changes the coach could seriously be making in the short term to help out.
The Squad. While there has been a lot of changeover over the last 4 years or so, the fundamental flaw in the squad is the lack of athleticism, attacking players and those that are not injury prone. We have a number of defenders, but barely anyone who can operate in the forward positions and also within the midfield / wing back options. Injuries also add to this. Meaning we have very limited options for who can actually play there, and offers something in an attacking sense. Dorgu suspended and Amad out means yet another game of Dalot and Maz, and with what was available I fail to see any other reasonable options he could have chosen instead. The squad is weak, and has been for a long time now and wasn't playing particularly well under ETH either in a different system.
There are things he could absolutely doing better, and I would have expected more of an improvement in coaching. Hojlund has shown very little and to keep playing him has been a mistake in my view. So too not using more of the youth players, with both Obi and Heaven showing something yesterday and should be playing more minutes from now on. He also doesn't help himself with some of his statements or with some of his subs in game.
But in equal measure some of the goals we concede we have seen for years, and I think comes down to more than just what the coach can affect. Many players aren't good enough to play for us, or don't have the character to. While he might be able to improve them, I think it's fair to conclude many can't be.
I don't expect everything to be sorted in one fell swoop, I think he absolutely needs time Amorim (certainly until at least next season) as we need a big window for sales and to see what we can bring in. More time with the squad will help, while I accept there hasn't been enough of an improvement. But I genuinely don't think we are as bad as we were back in January, while still not great I think the real lack of quality or options in midfield is really hurting us and would go some way to seeing a re-direct in results.
So yes, I think for now at least we need to suck it up.
