I was actually going to make a similar post, @Dave M609.
(Firstly, I dislike the 4-4-2 and a target-man -- at least traditionally; a wide target-man is more interesting to me, e.g Mandzukic. I like forwards that are mobile, that can come deep but more importantly stretch play.)
I think 4-2-3-1 suits two of our best players, in Kent and Hagi.
The other wide position, though, I didn't like the sound of another 'winger' -- too easy to deal with, and doesn't help the one up top. I was thinking of another forward for that position, who could come inside to make it two at times and help create. A player like Mandzukic at Juventus. I think Kamberi can play there -- and deserves to play, going by his most recent performances. (Is he still with us? I do hope we sign him up permanently.) Kamberi also suits the Raumdeuter role too.
I like the idea of Jack sitting, with Aribo next to him as a box-to-box player; allowing him to use his ball wining ability alongside a license to get forward at times.
I think we'll need width on the right from Tavernier, with Barisic staying back a little more -- he has a good deep cross, anyway, and it maybe opens up a long shot at times.
I like the 4-3-2-1, but I don't think it suits Kent. I would drop him for those games where it's employed. It needs someone else to play alongside Hagi. We could even bring in a forward, changing it to a 4-3-1-2-type formation.
