Hi Cristiano,
here is my contribution to optimize your file... There are a few little mistakes that can be corrected quickly:
Championship:
Barnsley FC: GK kit: color of shirt/short name
Serie B:
team name: It's AS Cittadella, with two T.
kits: Benevento and Pisa: shorts numbers missing.
LaLiga 2:
team names: It's Alcorcón and Almería
Bundesliga:
team names: SV Werder Bremen, FC Ingolstadt 04 (just optional)
players: Manneh (Werder) missing.
managers: HSV fired Labbadia, new manager: M. Gisdol
kits: Gladbach is wrong (at least in my download file)
names: J. Vestergaard has been renamed to M. Hinteregger. Just reset the player name.
Other teams:
Classics:
European classics: kits: 1st: color of shorts numbers, 3rd: color of shorts/shirt numbers
World classics: kits: 1st and 3rd: color of shorts/shirt numbers, 3rd: color of shorts numbers
Other European teams:
team name: It's Shakhtar Donetsk. Its manager is wrong, too. It is P. Fonseca from Portugal.
Rangers FC: wrong manager. It's M. Warburton from England. You could set Celtic as rival team.
Celtic FC: You could set Rangers as rival team.
Fenerbahce SK: 3rd kit: color of shirt/shorts numbers
FK Rostov: Manager is from Moldova, not from Austria. shorts numbers missing. Squad: Ezatolahi and Azmoun are duplicates in the Iran NT.
Legia: It's Legia Warszawa, not Varsovie (french for Warsaw).
New manager: J. Magiera from Poland. GK kit: wrong color of shirt/shorts numbers.
Squad: Kucharczyk has overwritten Aleksandrov from Bulgaria NT. So Kucharczyk (Polish player) is in Bulgaria NT... Kucharczyk can replace the created Alexandrov and the real Aleksandrov from NT can be moved to the squad.
Ludogorets: manager wrong. It's G. Dermendzhiev from Bulgaria.
kits: missing sponsor on home kit (kit outdated?), GK: wrong color of shirt/shorts numbers.
National teams:
Europe:
Slovenia: home and away kits: chest numbers missing.
Hungary: GK kit: chest number missing.
Iceland: It's J. Gudmundsson, not Guthmunds-son (mistake of Konami).
Africa:
Egypt: home kit is from Marocco NT.
South Africa: kits are missing completely.
Asia:
Iraq: home kits: shorts number and emblem problem.
Japan: home kit: chest number missing.
North Korea: home kit: chest number missing, away kit: chest and shorts number missing.
South Korea, Thailand, UAE, Uzbekistan: kits missing completely, wrong player names
New Zealand: kits missing completely.
That's all I found. Hope you will erase these errors in the upcoming updates.
At the end a personal wish: could you correct the shirt player names of Borussia Dortmund? Weigl, Mor, Dembélé, Aubameyang, Sahin, Passlack, Pulisic, Bonmann and Park (correct shirt name: Jooho) are wrong.
And rename Bartra to M. Bartra?
Dembélé also has a commentary name...
There is always room for improvement.
