System-Driven Football
FM27 · Take an idea
onto the pitch.
Open competition in the Süper Lig. Places for young players in the lower leagues. One shared youth challenge in the Turkish Cup.
Türkiye lower leagues included · Database 27.0.0 · New career
An article. A point of view. A playable model.
Let’s try the structure I want to see in Turkish football inside Football Manager 27. I have turned the development model from my own article into a single FMF, integrated with Türkiye Alt Ligler v2.
Sınırlarla Değil, Sistemle Gelişen Futbol: Gerçek Reformun Anahtarı
In my article of 31 May 2025, I proposed a sustainable structure that gives young players opportunities on the pitch and assigns different roles to each tier, from the Süper Lig to amateur football. This patch is a playable FM27 adaptation of the structure I believe Turkish football should have. It does not represent official TFF regulations.

The further down the pyramid you go, the more room there is for young players. Promotion also changes how you plan your squad and develop talent.
The top of the pyramid
Süper Lig
- Starting XI
- No youth or domestic-player requirement.
- Matchday squad
- At least 1 U23.
- Player eligibility
- No foreign-player limit.
A bridge to development
1. Lig
- Starting XI
- At least 1 U23.
- Matchday squad
- At least 3 U23 players trained in Turkey.
- Player eligibility
- Up to 5 foreigners in registration and matchday squads; all must be U23.
More room for young players
2. Lig
- Starting XI
- At least 1 U21 and 3 U23.
- Matchday squad
- At least 2 U19 and 6 U25 players trained in Turkey. Up to 11 players aged over 28.
- Player eligibility
- No foreign players.
A stage for young talent
3. Lig
- Starting XI
- At least 1 U19, 3 U21 and 5 U23.
- Matchday squad
- At least 4 U19 and 6 U25 players trained in Turkey. Up to 11 players aged over 28.
- Player eligibility
- No foreign players. Players on amateur contracts cannot play.
Where development begins
BAL & amateur leagues
- Starting XI
- At least 3 U19 and 5 U21.
- Matchday squad
- At least 5 U19. Up to 8 players aged over 28.
- Player eligibility
- No foreign players. Players on amateur contracts can play.
One cup. One shared youth challenge.
Turkish Cup
Every team must start at least 1 U19, 4 U21 and 7 U23 players. The same requirement replaces the previous cup quotas that varied by league.
Turkish Super Cup
No additional age, foreign, domestic or homegrown-player quota.
How the model is implemented
Age groups overlap
An U19 player also counts towards U21 and U23 requirements. The cup’s 1/4/7 rule does not require 12 different young players: 1 U19 + 3 additional U21 + 3 additional U23 is enough.
The U29 target assumes a full 21-player squad
2. Lig and 3. Lig allow up to 11 players aged over 28; BAL and below allow up to 8. In a full 21-player matchday squad, this ensures at least 10 and 13 U29 players respectively. Smaller squads do not guarantee the same youth totals.
U19 is an age requirement
The combined U19 + club-trained condition in my article is not enforced in this version. U19 is based directly on age. The U23 trained-in-Turkey requirement in 1. Lig and the U25 requirements in 2. Lig and 3. Lig are enforced.
One file. A new career.
99 is the season registration limit, not the matchday squad or substitute count. The game determines age eligibility using its seasonal cutoff dates. The patch cannot be applied to an existing save.
Sistemle-Gelisen-Futbol.fmfTürkiye Youth Rating 200, Fenerbahçe staff/facility edits and injury patches are not included. This file does not raise youth-production ratings or facilities. Financial values are retained from the source lower-league file.

Before your first season
Should I enable Türkiye Alt Ligler v2 separately?
No. The lower-league base is already inside this single FMF. Disable the separate Alt Ligler v2 file.
Does this reproduce actual Turkish league regulations?
No. It adapts the football development structure proposed by Burak Karaca in his own article. U19 homegrown and U29 implementation differences are explained on this page.
Does it generate better young players?
It does not directly increase youth-production ratings or player potential. It introduces rules that create places for young players in squads and starting elevens. Türkiye Youth Rating 200 is a separate patch.
Can I combine it with the Global foreign-player freedom patch?
No. Both change Turkish league rules. This FMF includes its own age and foreign-player model.
