I don’t quite see it as Bluebells set up.
I tend to agree more with
@Frogfish and
@Fabio in that we’ll see Wirtz in more of the Don role, but whereas Don tends to drift out to the right, Wirtz will drift to the left.
But again - with Kerkez & Frimpong, he might not need to and if Mac & Gravy form a double pivot he’ll stay central.
When I mean fluid, I mean the one thing we can say with confidence about Slot is that he will vary the set up - trad 433, read 4231, false 9, trad 9 and trad 20, double 10, double false 9, inverted wingers, inverted FBs - whatever system you want to make up - he’s not welded to one set up.
That also means he’s more interested in players who are positionally flexible, I think.
I’d say our system is going to be more PSG-styled than anything.
