I feel like there has been such an obvious problem in this 4-3-3 he persists with ever since Jack got injured...
No one will pass through the middle, run through the middle, and it's so easy for a team to know it won't happen and just press the wings, because guess what we'll just pass it back to CB and they (instead of walking through the space in the middle right in front of them) will just hoof it up field to give up possession.
With Jack in the team, we'd exploit the middle of the pitch, players would have to come towards Jack, and he'd then move it to an open man. No one else does that, so we end up completely spread towards the sides of the pitch, and it's easy to defend and even easier to attack against.
I'm a fucking moron, have no professional footballing experience, yet it's clear as day. Why don't we make adjustments until Jack is back?
