Yeah but it's silly to hold the current regime accountable for the failings of previous regimes (see also Marco Silva and Everton). We don't have anyone worthy of a call up other than Pickford. Keane's played well for about 3 games, Davies has been decent but not amazing, DCL is a bit of a quandry.
I think Davies has shown more than Harry Winks for example in terms of getting a call up.
It's those closer calls that go to the player at the bigger, more beloved by pundits type of clubs. I don't think you could really say Barkley has done much barring his most recent game that really merits a call up, and he already had been selected by that point.
