This feature was available in the previous iterations of FUT, with EAFC 24 Coins lines connecting each player, and changing color from red to green to symbolize chemistry.
It now has three diamonds on each player Amdash; these will light up if you have a connection with a close teammate in your position, allowing you to have up to three chemistry points per player.
Chemistry is built by having players from the same country, team, and league. You will gain a chemistry point for each similarity they have.
You cannot put players out of position, or they will always have zero chemistry (this is shown with an exclamation mark). You can change them into that position, but you need a consumable to do so.
You can use loan players in the game that only have a certain amount of games they can play.
However, it can be easy to rely on them as they are usually high-rated players. If you rely on them too much and build a team of loaned players, you are going to be in for a shock once the contracts run out, and you are left with a normal team.
With normal players, you can add contracts to make sure they can play for the team. Loaned players, on the other hand, are done when their contracts are done, and they cannot be renewed.
Be careful putting too many loans in your team at once, and make sure you have a good backup once the contracts run out.
When playing the game, you will get some players and packs that are untradeable. This means you cannot sell them on, but you can trade them in when doing squad builder upgrades.
If you get players you can sell (tradeable), you have a couple of options. You can either Quick Sell for a EAFC 24 Coins for sale set amount the game offers or add them to your Transfer List.
