Agreed.
The 4-2-2-2 was a logical response to our early season issue, which saw our front 4 getting by passed and our middle and defensive thirds being overrun by everyone we played.
IF we played the 4-2-2-2 the way it was designed to played. For argument's sake, the RB Leipzig way. Then it would be difficult to play through the middle of us. This would force opponents down the sides of us, acting as a pressing trigger where the team can use the touchline to force the opponents into bodies. Or force them to play long balls and put the onus on our back line to win 1v1s.
However, besides the first half against Palace we have not seen the players picked as #10s in the 4-2-2-2 do the requisite work to make the system function as designed.
