You do have to wonder if there is more to the downturn in form. I think we can clearly see Poch is trying to change the way we play, gone is the high press etc which bought us some success but without silverware. Assuming this is the case, could it not be more that the players themselves are struggling with this transition, working under one system for 5 years and then moving to a different way of working cant be easy and is bound to lead to poor results and a lack of cohesion until its fully embedded. I think many have said, we have also worked with Eriksen as the main guy with peoples movement around giving him space to open up teams and to be the creative outlet, this obviously had to change and the fact we haven't looked for that type of player, but rather a more dynamic player with creativity spread.
Ultimately, there is a lot of work to do, there are clear gaps that need addressing which is impossible to do in one transfer window unless we settle for players rather then taking the right player. There are also things i dont like with the change, such as Son playing ahead of Kane - while Kane maybe trying to develop his game, it cant be at the expense of his goal scoring and general movement in the box. Still providing we are not getting relegated i am happy to Poch one season to embed whatever this new philosophy is, to see if it can take us up a level and if it means i have to put up with a season not as good as the previous ones so be it, he has earned that right by punching above our weight for so many season successfully.
I am interested to see what happens in Jan, as i think full backs and possibly another CB is key right now and addressing those gaps (maybe even a Dybala or Fernandes if they are available) may tell us more about what the actual plan is.
Short/Short version: We are changing systems/play styles - this takes time and patience is needed for this to happen and to bring in the right people to make it work.
