Anyone’s who’s fussed with FIFA Ultimate Team will know how important chemistry is to the performance of your players.
Apply special chemistry cards to your players and you’ll increase their statistics. In 2016, EA Sports revealed the numbers behind chemistry, publishing a table outlining the attribute values a player with 100/10 chemistry receive, broken down by chemistry style.
That’s easy to understand, but the problem has always been the game itself did not show the player exactly how chemistry boosted player stats. All you could see were boosts to bundled stats such as “shooting”, not boosts to actual attributes within the bundled stat. So, you’d know your player had a boost to shooting, but you wouldn’t know which exact attribute, such as Finishing or Long Shots, were boosted. That meant it wasn’t clear, for example, whether you’d want the Sniper or Finisher chemistry style applied to your striker.
