1. Central Midfielders (CMs) & Defensive Midfielders (CDMs)
Role:
Central Midfielders (CMs) control the flow of FC 25 Coins the game, providing both defensive support and attacking creativity. They are the link between your defense and attack.
Defensive Midfielders (CDMs) protect the backline and break up opposition attacks. They provide stability and cover for the central defenders.

Links with Goalkeeper (GK): The goalkeeper and center-backs should have strong links, as they often need to coordinate to clear crosses and set pieces. A strong link between them boosts defensive solidity.
Links with Full-Backs (RB/LB): Full-backs often overlap with the center-backs, especially when the full-backs push up the field. Ensuring good chemistry between CBs and full-backs helps maintain defensive stability even when attacking.
Tips for Maintaining Chemistry:

Strong Links with Each Other: Your CB pairing should ideally come from the same league or nationality. For example, pairing a French CB with another French player from the same league will help strengthen the chemistry.
Manager Boosts: A manager who shares a league or nationality with your CBs can provide an additional chemistry boost, improving their overall effectiveness.
Positioning and Movement: Try to select CBs who complement each other in playstyle. For example, a fast and agile CB works well with cheap FC 25 Coins a stronger, more physical CB.
