Tactics I know you've basically shown a haram ball line up there but what you're describing is basically a 4-2-2-2. The problem is that the full backs are not 4-2-2-2 fullbacks, they're CB working as fullbacks specifically so that they can invert.
We've started to pack our midfield in a similar way to Pool now and play less of a box and more something like a 3-5-2 in posession. Sometimes we do the double invert and have MLS + Timber join a DM and the wide forwards join Odegaard and we basically get the reverse of the box midfield, an MW formation which is what happened with Ipswich. This packs the midfield way too much but as a result the CMs have more license to roam forwards which we saw with Odegaard's and Merino's shots in that match (Ode shoulda finished better his own great work).
I like our options with Leo and Kai as 2nd strikers, the latter's goal was a direct result of this changed setup. We need that pure CF now that can fit this structure.
Gabimart was a disaster this match despite again trying very hard. Can't fault his effort but with the way we play now I'd say give Ethan a try for that slot.
