100% agree with this, great post.
Effectively gives them an extra man, mainly in midfield, so our wide players are forced inside leaving our full backs hopelessly exposed.
And to make matters worse, in possession the plan is for us to play a fairly slow tempo passing game in the areas that we're outnumbered.
Leicester are the only team I can think of who have had success recently playing 442, but they tended to bypass midfield and use Vardy's pace and Okazaki's energy. Plus, it helped that Kante does the work of three men in midfield.
