Club XI OptimizerShort version: for each spot in your formation, CIX rates every player you own by how well their attributes and PlayStyles fit that specific role — measured against your own club — then fills the team with the best available fit. It's a transparent calculation, not an opinion: the same inputs always give the same answer, and the Extension can show you why each pick won its place.
1The score
Every player is scored for a role with one formula:
total fit = attribute fit + PlayStyle fit (+ a role-familiarity bonus)
- Attribute fit — how the player's attributes match what the role needs.
- PlayStyle fit — how their PlayStyles match the ones that matter for the role.
- Role familiarity — a bonus when the player is naturally suited to that position+role (EA's ++/+), and a penalty when they're played out of position.
The XI is then assigned so each player starts in the single role they fit best, with no duplicates.
2Attribute fit — the 34 sub-attributes
EA describes a player with 34 detailed sub-attributes. The six headline stats you see on a card (Pace, Shooting, Passing, Dribbling, Defending, Physical) are just weighted averages of those 34. CIX scores the underlying 34 directly — finer than the six — and it weights them per role (a holding midfielder leans on Interceptions, tackling and passing; a striker on finishing and pace).
Each attribute is measured relative to your own club (how far above or below your squad's average it is), so "fit" reflects who is genuinely strong for the role in your team — not a raw number that punishes smaller clubs.
For reference, here is EA's own (public) breakdown of how the six headline stats are built from the sub-attributes — CIX works from the 34 underneath them:
| Headline stat | Built from (weight) |
|---|---|
| Pace | Sprint Speed 55% · Acceleration 45% |
| Shooting | Finishing 45% · Shot Power 20% · Long Shots 20% · Positioning/Penalties/Volleys 5% each |
| Passing | Short Passing 35% · Crossing 20% · Vision 20% · Long Passing 15% · Curve/FK Accuracy 5% each |
| Dribbling | Dribbling 50% · Ball Control 35% · Agility 10% · Balance 5% |
| Defending | Defensive Awareness 30% · Standing Tackle 30% · Interceptions 20% · Sliding Tackle 10% · Heading Accuracy (rest) |
| Physical | Strength 50% · Stamina 25% · Aggression 20% · Jumping 5% |

3PlayStyle fit
Each role has a prioritised set of the PlayStyles that suit it. A player fits better when they hold those PlayStyles — the more important ones especially — and an upgraded PlayStyle+ counts for more than its normal version. Your build-up style shifts the emphasis too: a possession plan leans on first-touch passing in midfield, a Counter plan on line-breaking forward passing.
4Where the priorities come from
CIX doesn't invent its priorities — they're grounded in three sources:
- Role attribute weights — from EA's own in-game role definitions (what each role is built to do).
- PlayStyle priorities — from the community best-PlayStyles-by-role reference, used in ranked order.
- Movement (how high/wide a role plays) — calibrated from real recorded matches, so a role's tendencies reflect how it actually behaves on the pitch, not just its label. (CIX Advanced.)
5A grade you can read
Alongside the raw fit, CIX shows a 0–100 grade that places a pick within your club's options (50 = an average candidate for your squad, higher = a standout). It's a club-relative reading, not a global ranking — it answers "are you fielding the best your club offers", which is the question that actually helps you.
6Why you can trust a specific pick
Rather than ask you to take the XI on faith, the Extension shows the reasoning on each starter:
- Why — the attributes that most drove the pick (e.g. "Short Passing · Interceptions · Standing Tackle").
- Shortlist — tap a player to see the next-best options for that spot and how they compare.
- Confidence — a "clear best" / "solid" / "close call" tag, based on how far ahead the pick is of the runner-up. Close calls are flagged honestly.
So when the optimizer disagrees with your gut — say it benches a high-rated name for a better role fit — you can see exactly which attributes decided it and by how much.
7What CIX deliberately does not do
It is not a cross-club power ranking, and it reads only the football data already loaded in your Web App — never your EA login or account details (see the Privacy Policy). It's an independent, community tool, not affiliated with EA.
