Almost similar to Guardian, but the difference is this Chemistry EA FC Coins Style can add +3 Finishing. It can be lucky if the defender takes a screamer kick

If you need a central defender who can build up attacks, you can take the Powerhouse. It can add Vision +3, Long pass+2, and Short pass +2.

Fullback/Wingback 
In modern football, a Fullback/Wingback is a player who must be able to create opportunities with his crosses. Besides that, fast speed is needed so they can do 1v1 with other players. The following Chemistry Style is suitable for Fullback/Wingback:

Catalyst

Catalyst can add attributes needed by modern Fullback/Wingback such as Acceleration +2, Sprint +2, Crossing +3, and long pass +2

Besides being able to add speed, Shadow can also add attributes to survive. This is important if your team is in defensive mode.

By using Artist, the player dribbling ability will increase by +2 and can add EA Sports FC 24 Coins passing attributes. This is very important if you want to build up from the flanks.
