Change in tone
how does it take 2-3 months to learn how conte wants you to play ?
are the players Thick or Lazy ? you go to a new job it takes time to understand how that company want's you to deal with stuff or their rules/regs etc, but you put the effort in to learn
yes the players learning will make mistakes but so do the experianced ones, with 5 subs Conte can try these players late in games
