Crossed out the Sweat thing because...I can't (or don't want) to go into my feelings about that.
Maybe. Or maybe they get in each others way. I, too, think they might work as a partnership. But I don't think I'm willing to shift our system to a 4-4-2 for it, and I don't know how you sacrifice Isi or Medina or Moralez at this point.
Maybe with a back 3-5-2, you could force some things. But even in that scenario, would you rather Berget and Villa be up top or Villa and Isi/Medina?
I absolutely agree that Berget is quality depth. That's why I said his role for now, assuming a healthy Villa, is probably best as a last gasp sub. So he spot starts with injury or comes on to knock some long balls down at the end. Totally a good situation for us.
Although, at this point, agree with everyone that his spot starts should mostly be wide with Medina playing as a 9.5. Seeing his positioning and Isi's unanticipated immediate ability to deliver a final ball, I don't mind Medina as a false 9 at all when Villa isn't there.
I've gone from lamenting us not getting a Firmino-type signing in to start now with a view to spelling Villa and replacing him next year, to thinking we may have stumbled into two guys who could potentially become that with Medina and Isi. Medina is the more likely, of course. He just needs to add goals. Isi doesn't quite have the same other-worldly pre-cognition abilities, and I think that's a steeper hill to climb. Perhaps, though, the hill isn't that steep if we look at it as the combination of the two filling those various gaps we have and will have.
TL;DR: For me, Berget is pretty much a late sub with a fully healthy squad because I won't sacrifice any of the other options to force him in.
