yet when we tried it against united it backfired spectacularly because without the right wing backs we cant get out at all.I think it is a general problem, prior to this season, if you compare Conte's points per game in games where he had 5+ days rest vs those where he had less there is consistently a huge difference. I do think other coaches are capable of putting teams out who can make their system work with multiple games per week, even if they don't end up winning the double doing it.
My opinion is that a 3 man midfield would make our defence less exposed, not more, because we'd be putting fires out before they reach our defence. It will also allow us to dominate possession more and win second balls. The 3 CBs may make our defence stronger but they make us weaker as a unit because we can't retain the ball or compete against 3 man midfields with similar fitness/fatigue levels.
