will he consider changing the formation? for me 4-3-3 is obvious. im pretty sure , mikel , cesc , matic , oscar , ramires all prefer this formation. who does 4-2-3-1 actually benefit? off the top of my head, only willian. and that's only if he plays centrally, which he doesn't more often that not, currently useless guys like mikel and ramires, will become acceptable options , more or less this . and sorting out the fullbacks, is all he needs to do , to improve the team drastically.
