Appear in the transfer market

Your free-player card appears in the transfer market when you turn it on.

How to do it

When your player card and free-player card are complete, open My Profile → Your details → Free-player card. In the last section of that screen, Market, turn on Visible in the market. The option starts off.

Teams see your name, age and information from both cards, such as your position, group type, availability and zones.
They never see your date of birth or email address.
You appear in the market only when both cards are complete and visibility is on.
The Free-player card row under Your details shows whether your card is visible in the market.
If you turn visibility off, your card stops appearing in new searches, but summons you already received stay active.

If the control is missing, check that both cards are complete. Return to My Profile → Your details → Free-player card to open it.
