Centre-backs (CBs) are the rocks of your backline. They are the anchor of your defense but can also chip-in on offensive set pieces. The two attributes that you should focus on for when choosing the right centre-backs are Defending (DEF) and Heading (HEA). Good pace (PAC) is also a useful attribute to have. The higher these attributes, the better your defender will keep out the opposition.
Some of the best CBs in FUT are Thiago Silva, Giorgio Chiellini, and Sergio Ramos because they all possess these qualities. However, they’re quite expensive on the Transfer Market due to their high attribute ratings. A fun part of FIFA Ultimate Team is scouting the market for solid CBs that have good Defending and Heading and sell for a reasonable amount of coins.
Some reasonably priced defenders include Diego Godin, Aurelien Chedjou, and Ashley Williams.
