How to Play

UndefeatedXI is the soccer and football version of the 82-0 perfect-record idea: build an XI or full matchday squad from randomized football-history prompts, then see whether the side can go perfect, invincible, win the trophy, or fall apart.

1. Choose a Mode

World XI is the default. Champions League, World Cup, Premier League, and Ball Knowledge change the pool and target.

2. Choose a Formation

Most runs draft 11 fixed slots. Manager Mode extends the same shape with a rotation bench.

3. Spin Clubs, Nations, and Eras

Each round gives you a prompt. Pick a player, then place them into any compatible open slot.

4. Draft One Player Per Round

Take the legend now or gamble with scarce rerolls.

5. Rerolls

Most runs include one club/nation reroll and one era reroll. Some modes remove them.

6. Ratings

Source OVR is the original base rating or a labeled estimate. Gameplay attributes such as ATK and DEF are derived from source attributes, not copies of OVR. Historical pools combine era-specific base ratings, career Icon/Hero references and clearly marked estimates.

7. Chemistry and Tactics

The engine rewards a real spine, role balance, same-team links, and tactical fit.

8. The Simulation

Domestic modes chase perfect seasons. Tournaments track trophy status and perfection separately.

9. Result Grades

Perfect is rare. Invincible is excellent. Broken teams get exposed.

Player data and corrections

Current club rosters and positions use a dated snapshot of EA’s public base ratings. This is not a live transfer, injury or form feed. Historical club and national-team eligibility requires separate membership evidence.

Base Icon/Hero references are community-published by FIFPlay and describe a career, not an exact historical season. Players without rating coverage retain labeled estimates; broad historical position labels may also be uncertain. Send corrections with the player, team and era through Contact.
