I haven't tried out loads of defenders on this FIFA version but I've tried Eder Militao, Varane, Rulebreaker Alaba and Cordoba.
Yet - Lucio is the best defender I've tried out. He is always there when I need him.
Intercepts the ball, uses his strength and he is very good to head the ball away from corners and crosses.
His marking is also most of the time on point.
Nobody is going to dribble with him but he have very good dribble stats for being a CB.
In my opinion he would fit in all formations. Five, four and three at the back.
He will be bossing around in the defense. And yes, he is lengthy.
- Dribbling (could be good to get out of sticky situation)
