With Minamino off to Monaco we look an attacker light. I can't imagine the plan is to play 17-year old Kaide Gordon in those minutes.
A switch to a 4-2-3-1 seems almost inevitable. With Nunez, Jota, and Firmino, have three guys who can play the #9 in that formation, and Harvey and Carvalho are much more natural fits for the three attacking midfielder roles rather than as wide forwards. Jota and Nunez can also play in those wide attacking positions, providing depth for Mo and Diaz. Then we have Fabinho, Hendo, Keita, Thiago, and Milner (welp) for the double-pivot, and potentially Ox if he stays.
The biggest question mark imo for that formation is who plays the #10. Harvey is the most natural fit but it would be putting an awful a lot of responsibility on him. Thiago would be interesting there, and it would mean less wear and tear on an older, injury-prone player but you'd be moving the best deep-lying playmaker in the world out of position and playing him in a role he's never really played before.
Gonna be really interesting to see what Klopp does with our formation.
