I feel this needs a bit of steering to avoid popular players being repeated. So am making some changes to the criteria:
Box 4:
Dutch Flair "Currently plays in Dutch League"
is being replaced with
Divided Kingdom "Player from UK excepting England"
Guidance: Player must have been born in and played for Scotland, Wales, N.Ireland NT. Player must NOT have played for England NT
Box 11:
EFFICIENT "Currently plays in Bundesliga"
is being replaced with
Hey BABE! "Managed by Sir Matt Busby (exclusions apply. see guidance)"
Guidance: Should have played (have game time) in at least a single game under Sir Matt Busby for Man Utd. The trinity (Law, Charlton, Best) and Duncan Edwards cannot be picked.
..............
Will think of some more. Opinions welcome.
