I felt, that the end of last season, where he reverted back (to a degree) was also an adaption. Same for this year, where how we set up looks more like his first season. But it is difficult to tell for now, given that Eriksen is an important player and how he plays influences the team. Might just as well be the case that his lack of mobility makes the formation look different, who knows.
I get that it sounds very plausible, that he is that stubborn guy who tries to get his will against all reasonable considerations. I don't see that to be the case, I'd agree through the middle of last season, where the injuries were high, I also thought he should adapt now as the player material was obviously not suited but overall, I think there isn't much to back that claim of being overly stubborn. And to be perfectly honest, I am actually thankful he isn't just ripping it apart right now due to some suboptimal results. We need to break some of those blockages, as long as we always get back to "keep it simple" as soon as there is some discomfort, we aren't going to evolve.
As said in another thread (I believe) I think it comes down to what exactly are the expectations for this season. I haven't seen us being relevant in any way shape or form, probably thats the main reason, why I am less impulsive about the results. I mean, I get it, the results are certainly lacking but it will be a difficult task for any manager to simultaneously repair the broken bike, tune it to improve its performance and try to get into top 4 of the competition, where opponents already have mostly tuned up bikes. I am not hanging on ETH, but I don't think, there is much hope for significant change. Obviously, if we are dumb enough and bring in some hottalker who'll setup with a deep block and have us countering, we aren't going to lose as often. Looking at the current threads, maybe we really have to re-do that cycle once again so a few more will take the lesson.
You are away that every sacking comes with a payment to the sacked manager, aren't you? It is going to cost a lot, just to "give it a shot" and when the successor fails, there will always be enough fans to ask to give him a transfer window and lets see from there. The decision how to replace ETH is very important and we if we don't get it right, it can mean even more time wasted.
