I don't entirely disagree, mate - I'm not very convinced by Barkley either. But that very Englishness that has seen him hyped also has certain advantages in terms of keeping his valuation high in the event that he turns out to be a dud and we have to subsequently move him on - plus, it's a low risk transfer on our end, because we have a dissimilar, but very capable replacement for Dembele anyway in Winks. If he works out, great. If he struggles, maybe try him out at AM and see how he does there in a more attacking role. If he still struggles, convince some other English club that he's a diamond in the rough and move him on for a relatively inflated fee.
All this is predicated on him coming in for a 20-25 million pound fee, mind (because of his contract situation) - if Everton want more than that, then even those possible upsides become *very* difficult to justify, and we'd be better off plumping for Goretzka, Kessie or someone like that even at the risk of them not working out and netting us less than Barkley would in that situation.
With Goretzka, he's very attainable, I think. Schalke are struggling to rise above mid-table, and a move to the Prem might help him gain the exposure he needs to get into the German national team on a consistent basis. However, by the same token, maybe he won't want to move in a World Cup year (because of the fear of being benched at Spurs and then duly passed over by Low come 2018)? I dunno. But he's more attainable than Isco was, and than many other similarly talented midfielders with the 'Dembele' profile (big, strong, good on the ball, good defensively, etcetera) would be - players like Bakayoko and Nainggolan.
