We've spent the last 10 years replacing players as well. Doesn't seem to have helped any more than replacing the managers has.
It's obviously a possibility that both the players and the manager can be a problem at the same time. And based on what we are seeing it's not just a possibility, it's a strong probability. In which case, why allow a failing manager to continue training and managing the club which will likely result in another 12 months of failure, training a system that isn't working, and have influence on the transfer targets?
With the new football structure coming in I would hope that they already have a decent idea what the priority changes need to be, so a new manager will come into the club already being told that certain options will be changing. Sure they won't have as good a hands-on idea as ETH does, but that could perhaps be a good thing if ETH has formed attachments to players who aren't good enough.
Yes we have spent the last 10 years buying players without a good sporting setup.
That have now left us with players like AWB, Lindelof, McGuire, McTominay, Rashford, Bruno who are not able to play possession football with a high defensive line.
But I guess they could do great if we get in a Simeone, Frank or someone else who are great at parking the bus (but not football worth watching and we will then get more of that type of players in).
I do not believe that we will get a clear out of players with a new manager as he will want to assess all the players before deciding which he believes in. And that will be the end of that transfer window.
I do agree that ETH do not seem to be the right manager but I still prefer to get a clear out of the players that did not show up vs Brentford etc. (it is not on any coach if players do not want to run back or cannot do a 5 yard pass).
