Nah, I'd disagree with you there to some extent.
Last season the entire structural system of the team was never going to work. We could have had some of the best players of all times in every position and it still would have failed. It was unbelievably naïve and incompetent from ETH to continue on with that all season (at least until the last four games). Based on our performances we should have finished significantly lower than what we actually did, but individual player quality bailed us out enough that we managed to finish 8th instead of 14th.
This season the general system and formation is workable. It's just the specific tactics, patterns of play and general coaching that is failing. So we've improved the most obvious and glaring problem, now we've just got all the other ones. Based on our performances we should be a bit better than what our actual standing on the ladder currently is.
So there has been an improvement. Just it's an improvement from 'unbelievably shit and worst season in the PL era' to 'still bad and nowhere near good enough'.
