Fine, but in that case (I.e. Dier as a CM) I'd rather focus on having a backup with Alli's skill set (which I think it's fair to say is more about goals than physicality). If he's also more adept than Alli and Eriksen at playing CM in a pinch then that's great, but I think that should be the order of the prioritisation.
I don't watch European football, so don't know if those guys you mentioned fit the bill!
Well, the thing is, if we stick with the 3-4-2-1 (or some easily-swappable variation of it), then we already have an Alli approximation in Son - who's also more about goals than physicality. The other AM position, Eriksen's, will possibly be reinforced by Lamela returning to take up the role of being Eriksen's backup - he's got a roughly similar skillset in terms of corners, passing (short and long) and drive in the final third, although maybe without Eriksen's clinical finishing or ability to control the tempo.
The thing about advocating for a Dembele-clone is that the player's versatility will allow for replacing any of Wanyama, Dembele or Alli in a pinch, or in the event that a surplus of fully-fit, in-form options restricts his playing time in one position (DM, for example, or AM) - but that requires that he have a skillset that suits that sort of jack-of-all-trades role. To me, that necessitates being a CM more than an AM, although of course that's just my opinion on it.
I suggested to my mates they should sign Vorm
redmond has been their stand out player hence why he has got in the England side (I know that's not the best measure). He has scored more goals for them than Lennon ever managed for us in a season for example. Has a. Erg high pass success rate too at 84%. He is as quick as someone like Zaha but IMO may cost less and is much more of an overall threat
We do not need cover for cover in midfield unless it's a very versatile player - I can't comment at all on the lad Goretzka as I've never seen him play
Oh, I agree, versatility is key in any midfielder we bring in this summer - but re: Redmond, I'm not as convinced. Purely because, as I mentioned to
@elltrev - we have four AMs to fit into that 2-man attacking band behind the striker in 3-4-2-1 (Alli, Eriksen, Son and Lamela in that order), not counting Onomah or Edwards if they merit the minutes. Lamela might not be here next season, but then, including Onomah and Edwards, that's still 5 for two positions. If we switch to a 4-2-3-1, then N'Koudou, Sissoko and co. also come into the picture as backup AMs/wingers for those three AM positions.
Point being, it's pretty crowded in our AM band. Now, that doesn't preclude bringing in a new AM, of course - but if we're going down that route, swapping Lamela out for a relatively cheaper, more raw option in Redmond seems counter-productive to me. Why not go for a more established, expensive player to challenge Alli and Eriksen from the off, in that case?
I see the parallels between Redmond and Zaha that you're drawing - but I'm equally dubious about the prospect of bringing in Zaha as well, for the same reasons.
As for Goretzka, I watched a fair bit of him this season because of tuning in to see how Bentaleb was doing at Schalke. He's pretty solid as a midfielder - roams across the midfield while Bentaleb holds things down, and can tackle, press, pass, dribble and score with relative ease - while being an imposing physical unit to boot, and very vocal on the field.
