How to build a working squad in Fifa 23
The squad builder sits behind a chain of interlocking rules, and most people blow through it without understanding the actual constraints. Here is how it works on the ground level. You place players into formation slots, each slot carries a position and a zone, and the game calculates chemistry from three separate sources: links between adjacent players, the player's actual position versus their slot, and nation/league/club relationships. The final number ranges from zero to three per player, and you add them all together for the team total. A completely broken link costs you two chemistry points per connection, which cascades across the whole formation quickly. I spent about forty minutes last week trying to fit a hybrid league squad around a specific striker I wanted to use, and the problem was that the winger I placed on the left had a silver link to both the midfielder in the slot above him and the defender in the center. That silver link alone dropped his individual chemistry to one, and the midfielder next to him also fell to one because of the same connection. I had to pull one of those players out and replace him with someone who shared a green link to both positions, which meant finding a player from the same league but a different club so the link would register as green instead of silver. It took about twelve minutes once I understood the link color system properly.
Fifa 23 Squad Builder Chemistry
Chemistry exists to reward logical squad construction. The system gives you bonuses when players share nationality, league, or club, and it punishes you when you force incompatible players into adjacent slots. Positional integrity matters more than people realize. A striker played in a right winger slot does not get the same chemistry bonus as a proper right winger, even if the player's actual position says forward. The slot determines the relationship, not the player card. Links operate on a color system. Green means full chemistry benefit, silver means half, and red means none. The game evaluates links horizontally across the front line and vertically down the middle. Diagonal links do not count at all, which surprises a lot of builders who assume every neighbor matters. The tricky part that nobody explains clearly is that a player can only receive chemistry benefits from links that actually connect through the formation grid. If you swap a player out and the new person has a different league or nation, every link in that area recalculates instantly. I have lost teams mid-build because I swapped a center back for a cheaper alternative without checking that the new player's nation still matched the goalkeeper's. The whole back line dropped by four chemistry points in one click.
Position roles and chemistry calculation
Each formation slot has a primary position, and when you place a player whose actual position matches the slot, you get a chemistry boost. When the slot and position differ, you lose it. The game checks this relationship separately from the link system, so two players can have perfect links and still end up with reduced chemistry if their positions do not align with their slots. A common mistake is assuming that a center forward can fill a striker slot without penalty. In Fifa 23, that works fine, but a defensive midfielder placed in a central midfield slot does receive a small penalty because the game distinguishes between DM and CM roles. The difference is subtle, usually one chemistry point, but it adds up across a full squad. The manager slot adds another layer. Managers provide a fixed chemistry bonus based on their nation and league affiliation. A manager from the same nation as your goalkeeper typically gives a small boost to the entire defense line, and a manager from a major league like the Premier League tends to help most squads regardless of your actual players because so many top players come from that competition.

Build strategies that actually work
The most reliable approach is to build from the center outward. Start with your striker and center backs, lock in the nation and league connections there, and then fill the wings. This way you know the core chemistry before you add peripheral players who might disrupt it. Hybrid squads are possible but expensive. You can mix two leagues if you find players who share both a nation and a club connection, which creates a green link that bypasses the league restriction. I built a squad last month with players from two different leagues by using a center back who happened to play for a club in one league but was from a nation represented in the other. The green link through nation overrode the league mismatch, and both players maintained full chemistry. The limitation is that hybrid squads rarely reach the theoretical maximum. A pure league squad can hit 33 chemistry easily, but a hybrid might cap out around 26 to 28 depending on how many players you can force into compatible links. The game simply does not have enough overlap between nations and leagues to make everything green.
Common pitfalls
People overlook the goalkeeper link. The goalkeeper connects vertically to the center back in front of him, and that link carries into the entire defensive line. If your goalkeeper shares a nation with your center back but not the league, the link goes silver, which ripples through the whole back four. Another frequent error is placing wingers too wide. The left and right wing slots connect to the center midfielders horizontally, and those connections often break when the winger comes from a different league than the central midfielders. Builders usually fix this by switching the winger to a different player or moving the central midfielder to match. The squad builder also penalizes you for using players out of position in ways that seem minor but actually stack up. A right back playing at center back loses chemistry not just from the position mismatch but also from any link that the center back slot would have provided to adjacent defenders. It is a double hit.
When the system fails you
Chemistry works well for balanced, conventional squads. It breaks down when you want to build around a single obscure player from a smaller league with no nation or club connections to anyone else. In that case, you are likely looking at chemistry in the high teens at best, and the team performance will reflect it. The workaround is to accept the lower chemistry and compensate with higher overall ratings, or to build the squad differently around a more connected player. The alternative if chemistry is dragging you down is to focus on player stats and formation shape instead. A well-positioned team with mediocre chemistry often beats a theoretically perfect squad that lacks pace or physical strength. The chemistry system rewards logical construction, but it does not guarantee competitive performance in matches.
