Like others, I'll be amazed if Slot messes with the midfield and I think Wirtz will take one of the the striker spots in the squad but be used as a false nine/ten. I think he'll be expected to start moves and then burst forward to the box to also try and get on the end of things. His goal for Germany last night epitomised this and we know he can finish for fun. We will be playing a system that maximises all his strengths, which won the battle of the sales pitches.
In a sense I think we'll play him as a Firmino/Jota hybrid type player.
-------Gakpo--------Salah
------------------Wirtz
Kerkez---Mac----Dom-----Frimpong
---------VVD----Grav----Konate
---------------------Ali------------
It's all speculative though, but this is what I reckon we would have pitched to Wirtz and it won't be liable to change no matter what happens at LW.
Out of possession I'd expect Slot to maintain his 4-2-4 set up with Wirtz and Dom joining the first line, Grav stepping forward to Mac Allister and the fullbacks dropping back into shape.
