Too early to be writing us off completely, especially after the slow start last season, I think we have to be looking at a minimum of the top 4 and strong showings in the cups, anything less is just not good enough for the outlay, ETH will surely be working under the same understanding.
A good season would be top 3 and showing consistency in performance and not being outclassed by top 6 teams or in Europe, that would show the team is evolving and give us some belief that things are improving.
A worrying season would be just making the top 4 and little or no improvement in the side, there's no excuses for not improving, ETH can't make everything perfect in 1 season but we have to keep developing or we will flounder.
I don't think we can judge ETH until at least halfway through the season, the tactics have changed, there's been loads of off field trouble and we have a lot of injuries, those are not excuses but very valid reasons for an underpowered start to the season (as well as the number of games played last year etc) but it's ETH's job to get the best out of what he has so there has to be discernable improvement (not expecting miracles).
