Look at the games Miley's played - and before I go further I am not blaming the kid AT ALL but look at the factual stats:
https://www.transfermarkt.co.uk/lewis-miley/leistungsdaten/spieler/922769
11 games in the league before he was starting: Won 6, Drew 2, Lost 3 (City, Liverpool Brighton - at the start of the year)
15 games in the league he started (in a row because of injuries): Won 5, Drew 2, Lost 8
No way the kid - and he is a child, he can't even vote yet! - should be starting every game regardless. Need's must and the boy has come in and done wonderfully well given the pressure and experience he's had previously but he's not the finished article yet. Give him 4 years (he'll be younger than Gordon is today) and he'll be quality and probably ready to start most games at that point.
Longstaff was playing aswel so the stats tell you nothing.
Miley might be capable and longstaff isn't and never will be.
