Terrible hot takes
Change can be good.
Ultimately we need a formation that best suits the players we have at our disposal. Conte found the best possible formation for Chelsea, we've yet to find ours. 4-2-3-1 does suit us very well but we have to examine reasons as to why it's not been working.
I think we should go back to our roots of playing narrow since playing wide hasn't worked for us, it's leading to too many turnovers in possession.
The football manager gamer in me has an idea of a 5-2-3 formation with inverted style wing backs playing as narrow as possible, Alexis as the main attacking outlet in the #10 role (FM calls it a 'shadow striker') behind two supporting strikers, but I'm not sure how practical it would be in real life.
The FM gamer in me would like to try
a 4-3-3/5-2-4
but with Özil playing as striker ala Götze or Spain with several players
you can call Coq a CB or CDM doesn't matter he should sweep behind Ramsey/Xhaka or Ox who got license to go forward, Xhakas shooting is needed
