I am more worried about the fundamentals of professional top level rather than actual quality, there are issues on fundamental level that this squad suffers from, during the match, there are issues such as work rate, discipline, focus, determination, etc...
Ten Hag's main issue was he could not get them to be better on those basic stuff consistently, and his tactics and in-game management were terrible as well.
What I want to see from Amorim is to get these players to perform better and give it all, when that happens, then we will be able to determine the quality of the team, the technical level and tactical adaptability.
Look at Arsenal for example, what they lack could be quality in certain areas such as striker, LW, or LB, but what they do not lack is the fundamentals, as in they work hard, they are focused and disciplined, and so on, they get results on the board, if they fix some positions, they may mount a proper league challenge, compared to us, we do not even know if our squad can get us top 4, some good players but they never played well as a team consistently.
