Updated 16 September 2026. You do not choose an FPL formation from a dropdown. Your formation changes automatically when you swap a starting outfield player with a benched player from a different position, as long as the new XI remains legal.
The official FPL rule is simple: your starting XI must contain one goalkeeper, at least three defenders, at least two midfielders and at least one forward.
That means formations such as 3-4-3, 3-5-2, 4-4-2 and 4-5-1 are possible, but shapes such as 2-5-3 are not.
Quick answer
To change formation:
- Open Pick Team.
- Select the starter you want to move to the bench.
- Select the benched player you want to bring in.
- FPL swaps them if the resulting XI is legal.
- Press Save My Team.
You can then use OneFPL Team News to check whether the players you are starting are expected to play.
How to change formation on the FPL website
Suppose your team is currently 3-5-2 and you want to switch to 3-4-3.
You need to remove one starting midfielder and bring your third forward off the bench.
On the official FPL website:
- Go to Pick Team.
- Click the swap icon on the starting midfielder you want to bench.
- Click the swap icon on the benched forward.
- Confirm that the forward moves into the XI and the midfielder drops to the bench.
- Click Save My Team.
The formation changes because the position mix in the XI has changed.

How to change formation in the FPL app
The principle is the same in the app.
- Open your team.
- Go to Pick Team.
- Tap the player you want to substitute out.
- Choose the bench player from the different position.
- Save the team.
If the swap would create an illegal formation, FPL will not allow it.
Every legal FPL formation
Because you must field at least 3 DEF, 2 MID and 1 FWD, the normal legal shapes are:
| Formation | DEF | MID | FWD |
|---|---|---|---|
| 3-4-3 | 3 | 4 | 3 |
| 3-5-2 | 3 | 5 | 2 |
| 4-3-3 | 4 | 3 | 3 |
| 4-4-2 | 4 | 4 | 2 |
| 4-5-1 | 4 | 5 | 1 |
| 5-2-3 | 5 | 2 | 3 |
| 5-3-2 | 5 | 3 | 2 |
| 5-4-1 | 5 | 4 | 1 |
Your goalkeeper is separate from the formation notation.
Why won't FPL let me make a swap?
Most blocked swaps happen because the resulting XI would break the minimum-position rules.
Example: trying to bench your third defender
If your XI already has only three defenders, you cannot replace one of them with a midfielder or forward.
You would be left with two defenders, which is illegal.
Example: trying to bench your only forward
A 4-5-1 formation has one forward. You cannot remove that forward for a midfielder or defender because an FPL XI must include at least one forward.
Example: trying to field six midfielders
Your squad only contains five midfielders, and the formation rules also require the minimum number of defenders and forwards.
Can you change formation after the deadline?
No. Any changes made after the Gameweek deadline apply to the next Gameweek.
For GW5, the current deadline is Friday 18 September 2026 at 18:30 BST.
Check the full season schedule in FPL Deadlines.
Does formation affect FPL scoring?
Formation itself does not give a bonus or penalty.
A 3-4-3 is not automatically better than a 3-5-2. The better shape is simply the one that lets you start the players with the best combination of expected minutes, role and fixture.
Use Player Lab to compare the player you are starting with the player you are benching.
Formation and automatic substitutions
This is where the minimum-position rules matter again.
If a starter plays zero minutes, FPL can replace him with a benched player. But the replacement must keep your team in a legal formation.
Example:
- You start in 3-4-3.
- One of your three defenders plays zero minutes.
- Your first bench player is a midfielder.
That midfielder cannot replace the missing defender because your XI would then have only two defenders.
FPL moves down the bench order until it finds an eligible defender who played.
Read FPL Auto Subs & Bench Order Rules for the full process.
Does bench order matter when changing formation?
Yes, but for a different reason.
Changing your starting XI is manual. Bench order becomes important after the deadline if automatic substitutions are required.
Once you have chosen the formation you want, set the bench in the order you would want substitutes to enter, while remembering that formation legality can override that order.
Which formation should you use?
Do not choose a formation because it is traditionally popular.
Choose it by comparing your actual players.
A simple method:
| Decision | What to compare |
|---|---|
| 3-4-3 vs 3-5-2 | Third forward vs fifth midfielder |
| 3-5-2 vs 4-4-2 | Fifth midfielder vs fourth defender |
| 4-4-2 vs 4-3-3 | Fourth midfielder vs third forward |
| 4-5-1 vs 3-5-2 | Fourth defender vs second forward |
Use Fixtures for opponent difficulty and Player Lab for role, form, xG/xA and minutes.

Common formation mistakes
Leaving an injured player in because the formation looks better: start the player more likely to play.
Ignoring bench order: especially dangerous during European and cup weeks.
Benching attacking defenders automatically: wing-backs such as Jayden Bogle can have attacking routes that make them competitive with midfielders.
Using fixture colour alone: a secure talisman in a harder fixture can still be better than a rotation-risk player in an easier one.
