Well there's no accepted definition for what constitutes 'a managers' team'.
The fact is, every manager inherits a team that is not "their team" and must set about changing that as quickly as possible. However, its accepted as part of that process that results and performances need to improve in the short/medium term. I don't think anybody is arguing that each new manager should be able to change all 23 players each time, with no regard for results.
So we can go back and forth on this. My opinion is that enough of the team/squad are now "his" players to suggest we should be seeing some improvement. If you disagree, that's fine, but it doesn't make my argument disingenuous- I'm not trying to mislead people with it.
I'm not at the point whereby I'm actively calling for the club to replace ETH right now, but I do think his position should be under serious scrutiny. Believe me, I wouldn't care if we'd lost all of our league games, if we'd played brilliantly well. My biggest concern is that when we're bad, we're very bad - and our 'base level' seems to be very, very average.
Can you remember a "good" performance under ETH that suggests to you we're heading in the right direction? Barcelona at home, maybe? Newcastle in the League Cup final, maybe? Liverpool at OT? Problem is, I can barely remember any resoundingly comfortable victories, but I could reel off ten horrible performances under ETH right now without even thinking for more than a few seconds.
My current position personally is, things HAVE to improve by Christmas. I'm not foaming at the mouth, screaming for him to leave...but IF we still look a shambles tactically and/or results haven't picked up against the fair/middling teams, a decision might have to be made.
And actually...I'd argue its not really a requirement for me to say who I'd have instead to suggest that ETHs position should be considered. There's loads of options out there, the next superstar managers are out there, I don't watch any non-English football, so I couldn't tell you who they are! I hadn't even heard of Ange or De Zerbi prior to them coming to the Premier League, both have done well. Could we tempt Eddie Howe? Would he be worth a try?
